High-voltage generating circuit including charge transfer switching circuit for selectively controlling body bias voltage of charge transfer device
Provided are a charge transfer switch circuit for selectively controlling body bias voltage of a charge transfer device, and a boosted voltage generating circuit having the same. The charge transfer switch circuit may include a capacitor whose voltage is boosted based on first and second control signals, a first transistor connected between a supply voltage and the capacitor and having a gate receiving a precharge signal, a second transistor connected between a first node and a second node and having a gate connected to a terminal of the capacitor, a third transistor connected between the first node and a bulk voltage of the second transistor and having a gate receiving the first control signal, and a fourth transistor connected between the bulk voltage of the second transistor and a ground voltage and having a gate receiving the second control signal.
