Abstract
A system-on-chip includes a body bias voltage generator having a voltage divider and a filter. The voltage divider includes a switched capacitor circuit and a resistor circuit. The switched capacitor circuit operates based on a first clock signal and a second clock signal. The resistor circuit outputs a first voltage through a first node, which is coupled to the switched capacitor circuit and the resistor circuit. The first and second clock signals have a same frequency. The filter performs a filtering operation on the first voltage to generate a body bias voltage.
