Abstract: Integrated circuit structure responsive to being triggered to produce output signals at precise time intervals following points in the operation of a device. The circuit is adapted for accurate repeating operation, and provides a plurality of signals at different precise time delays. A discrete capacitor is discharged to a predetermined value (reset) by a voltage regulator at each triggering of the circuit, and at the end of a short time starts to charge so that the voltage thereacross forms a repeatable exponential ramp. A plurality of comparators are coupled to the capacitor and each produces an output when the capacitor voltage reaches the reference voltage for that comparator. The triggering may be provided by a circuit including a reset capacitor which responds to the change of levels of a signal derived from the device to alternately charge and discharge the reset capacitor. The voltage across the reset capacitor is applied to a pair of comparators which produce current pulses during the beginning of the charge and discharge periods of the reset capacitor for operating the voltage regulator.

Abstract: In fuel injection ignition systems, it is necessary to provide control of the open time of the fuel injector valves which varies with the engine speed. However, for efficient operation with a minimum of pollution, the relationsip of valve open time to engine speed is not a simple relationship, and factors other than engine speed are involved. It has been found that the open time should change with engine speed by steps not directly related to engine speed. This can be accomplished by providing a waveform which varies with time across a capacitor by a regulator system which controls both increase and decrease of the voltage across the capacitor. This voltage waveform, which varies with time and is independent of engine speed, can then be combined with a ramp voltage initiated at a particular point of rotation of the engine at the time the injector valves are opened. The valves can then be turned off when the combined voltage has the desired relation to a voltage produced by manifold pressure to provide the required open time for the injector valves.

Abstract: Circuitry for providing a constant current to a load includes a source of current and a regulating circuit interposed between the current source and the load. The regulating circuit includes a current shunting transistor coupled to the output of the current source and a feedback transistor also coupled to the output of the current source and to the base of the current shunting transistor. A diode connected between the current shunting transistor and the current source is chosen to have a dynamic admittance substantially equal to the transconductance of the current shunting transistor to provide the latter with unity voltage gain. A variation in current output of the source is accommodated by the current shunting transistor so that a substantially constant voltage at the output thereof is maintained. An output circuit including a transistor, coupled to the output of the current shunting transistor and to the load, and controlled by the output voltage, provides a substantially constant current to the load despite current variations from the current source.

Abstract: A bonding pad substructure in a semiconductor device prevents injection of minority carriers into the substrate during negative overvoltages applied to the bonding pad. An N-type isolated region is provided in a P-type substrate. A P-type region is provided within the N-type region, subtending the metal bonding pad which is on an oxide layer on the substrate. Shorts between the bonding pad and the semiconductor which may occur at defects in the oxide layer are thus limited to the P-type region, and negative overvoltages on the bonding pad reverse bias the PN junction so that deleterious injection of electrons from the Ntype region into the substrate cannot occur.

Abstract: A system for energizing an inductive load includes a voltage regulator for providing a constant voltage across the load until the current builds up to a particular value, and a current regulator which then takes over to provide a constant holding current at a lower value. The voltage regulator may include a closed loop for holding the voltage across the inductive load constant or may respond to a regulated voltage value to control a power stage for providing a constant voltage. The voltage across a sensing resistor in the power stage controls the crossover from the voltage regulation mode, to the current regulation mode and the current regulator automatically resets the reference to control the power stage to provide a constant current of a lower value through the load. The system can be used to supply current to coils of injector valves in a fuel injection system, and may include two power stages for supplying current to two banks of coils. The regulator system is switched from one power stage to the other during successive 180* rotary positions of the engine for both stages.

Abstract: A bistable circuit and shift register requiring less chip area and with greatly reduced current drain is realized with I sL logic gates. Each cell (28) of the register includes only four logic gates (10), connected as two binary R-S flip-flops, each gate consisting of a pair of merged PNP and NPN transistors. The two flip-flops are alternately energized by switching the current into the gate injectors in accordance with the phase of the clock signal. The use of fewer gates with simplified interconnections contribute to reduce chip area and current drain.

Abstract: Two matched lateral PNP current sources supplying operating currents to a monolithic integrated operational amplifier circuit each are comprised of transistors with segmented collector rings. The collector segments are interconnected with the collector conductors by fusible metal links which may be burned out or melted by supplying a pulse of high current through the fusible links. By selectively melting these links, the relative currents supplied by the two current sources may be adjusted during the measuring and probing of the integrated circuit chip prior to its packaging.

Abstract: DC biasing currents for a monolithic integrated circuit are obtained from a single regulated current reference source supplying current through first and second series connected diodes to establish points of reference potential. Some of the current source transistors which are referenced to this regulated current source have the base-emitter junctions thereof connected across the first diode, and the emitter current of these current source transistors is collected and added to the current from the regulated current source and supplied through the second diode. This second diode, with a larger regulated current flowing therethrough, is used to reference additional current source transistors for substantially larger currents without necessitating the use of high ratio area scaling of the emitter areas of these current source transistors.
