Abstract
Disclosed is a low-power negative voltage generator for RF switches, which is provided with a monostable trigger and a voltage-controlled oscillator before a non-overlapping clock circuit and a charge pump. The monostable trigger can change from a stable state to a transient state when a switch channel selection signal jumps; the clock frequency of the voltage controlled oscillator will be increased during the transient state of the monostable trigger, and after the monostable trigger returns to a stable state, its clock frequency will be reduced to the initial state, thereby ensuring that the circuit power consumption is reduced while the transient characteristic is high.
