Abstract: Circuit for coupling to first and second current paths in which differentially related currents flow for providing a single output current which represents the differentially related currents. The converter circuit is particularly adapted for use in integrated circuits and utilizes a single multiple collector transistor with interconnections of the electrodes and connections thereof to the current paths. One of the collector electrodes of the transistor is connected to the base electrode and the junction thereof is connected in one current path to control the conductivity of the multiple collector transistor. The second collector electrode is connected in the second current path, with the collector electrodes being of equivalent configurations so that the same current flows through each. The output current is derived from the circuit connected to the second collector electrode and is a measure of the differential currents, and has a direction which indicates the path in which the differential current flows.

Abstract: A relaxation oscillator which is suited for fabrication as a monolithic circuit and which uses a parallel resistive capacitive frequency determining network wherein a capacitor is charged and discharged between an upper and lower voltage level. As the capacitor is charged to a potential exceeding a first threshold voltage level supplied to a comparator switch, the operating state of the comparator is caused to switch. A current detecting circuit is included which detects a current that is proportional to the charging current supplied to the capacitor from a charge circuit. As the proportional current decreases in value below a predetermined level due to the capacitor being charged to the upper voltage level the current detecting circuit is disabled which actuates a control circuit for switching the threshold voltage applied to the comparator to a lower level. The actuated control circuit also disables the charge circuit such that the capacitor discharges to the lower voltage level at which time the comparator switches states to disable the control circuit whereby the threshold voltage level is switched to the first level. Thereafter, the charge circuit is enabled to enable the current detecting circuit and to charge the capacitor to the upper voltage level.

Abstract: A variable dwell ignition system comprising a circuit responsive to changes in engine RPM for causing the dwell time of the ignition system to be varied accordingly. The circuit is adapted to be connected to a sensor coil to receive ignition timing signals developed thereacross which are generated in timed relationship to the engine operation. The circuit provides for changing the direct current (DC) level about which the ignition signals are generated such that a threshold level is varied. As the threshold level is varied the dwell time of the system is varied respectively.
