Abstract

The present disclosure provides a pulse generator which generates a pulse train by mixing pulses of a first clock having a first frequency, with pulses of a second clock having a second frequency. Over a predefined time period, the combination of pulses results in a pulse train having an effective frequency which is between the first and second frequencies. A multiplexer is used to select which of the first and second clocks should be provided to the output. Depending on the desired target frequency, the multiplexer is controlled to mix differing amounts of pulses from the first and second clocks. A multiplexer is controlled by a control signal, which is generated using combinatorial logic using the first clock as an input. The pulse generator may be used, for example, as a clock for a charge pump.
