Abstract
Voltage generators with relatively low clock feedthrough are disclosed. A voltage generator can include a charge pump with a first set of two switches arranged between two voltages, a second set of two switches arranged between one of the two voltages and an output node, and a fly capacitor connected to the first and second sets of two switches. The voltage generator can include a clock generation circuit to provide clock signals such that the two switches of the first set transition state and the two switches of the second set transition state at different times. In certain embodiments, the charge pump includes a p-type fly capacitor connected to an output node by way of an n-type transistor. In some embodiments, a level shifter can generate a level shifted clock signal for the charge pump and includes cross coupled transistors to receive a regulated voltage provided to the voltage generator.
