Abstract:
A programming circuit and a control circuit for controlling a charge pump of a voltage generator system, the programming circuit comprising:means for receiving at least one input con trot signal; means for processing the at least one input control signal using at least a series of bias stages; means for generating at least one output control signal using at least a signal outputted by the series of bias stages; and means for outputting the at least one output control signal to the control circuit of the voltage generator system for controlling the control circuit in accordance with the at least one input control signal, wherein the control circuit of the voltage generator system includes a limiter circuit and an oscillator circuit, and wherein a first input control signal of the at least one input control signal is configured for exclusively generating a first output control signal of the at least one output control signal for controlling the limiter circuit of the control circuit and a second input control signal of the at least one input control signal is configured for exclusively generating a second output control signal of the at least one output control signal for controlling the oscillator circuit of the control circuit.
