    Abstract: An accuracy in the data transfer rate of 0.25 % is required according to USB specifications. In order to generate a clock signal, which renders this accuracy possible, the invention enlists the use of a clock generator unit that operates without quartz. The inventive clock generator unit comprises an internal clock generator (11), a pulse counter (17), which is connected to the internal clock generator (11), a pulse number memory (18), and a pulse filter (14). The pulse counter counts the number of the internally generated clock pulses between two pulses of the synchronization signal (16), which are transmitted according to the USB specification. The difference between the determined pulse number and a specified pulse number is evaluated and is used for controlling the pulse filter (14) that suppresses pulses, thereby resulting in the generation of a stabilized clock signal (13).

    Abstract: In accordance with the USB specifications, an accuracy of 0.25% is required for the data transmission rate. To generate a clock signal that allows this accuracy, the invention uses a clock generator unit that does not require a crystal. The clock generator unit includes an internal clock generator, a pulse counter that is connected to the internal clock generator, a pulse number memory, and a pulse filter. The pulse counter counts the number of internally generated clock pulses between two pulses of the synchronization signal, which are transmitted in accordance with the USB specification. The difference between the ascertained pulse number and a nominal pulse number is evaluated and is used for controlling the pulse-suppressing pulse filter. This results in a stabilized clock signal.

    Abstract: A frequency regulating circuit for the current-consumption-dependent clock supply of a circuit configuration includes a current measuring device for measuring the instantaneous current consumption of the circuit configuration, a controllable clock supply circuit, which can be connected to a clock input of the circuit configuration, and a control device for driving the clock supply circuit based upon the measured current consumption, an increase in the current consumption of the circuit configuration effecting a reduction in the clock frequency at the output of the clock supply circuit. Such a circuit ensures that a maximum permissible current consumption is not exceeded, but, at the same time, makes possible a maximum power of the circuit by a maximum clock frequency.

    Abstract: The circuit contains a series regulator with an FET. A capacitor and a further FET, which is provided as a transfer gate and is driven by the POR signal, are connected in series between the source terminal, to which the external supply voltage is applied, and the gate connection. When the external voltage is applied, the FET opens, with the transfer gate switched on, corresponding to the charging of the capacitor which now takes place. Because this charging process takes a certain amount of time, overshoots in the internal voltage are prevented.
