Abstract

See full text

Provided is a relaxation oscillating circuit, which comprises a charging circuit, a discharging circuit, a switch circuit, a charging-discharging capacitor and an output circuit. The charging circuit comprises a first current source and a first isolating transistor. The discharging circuit comprises a second current source and a second isolating transistor. The switch circuit comprises a main charging transistor and an auxiliary charging transistor arranged as mirror and a main discharging transistor and an auxiliary discharging transistor arranged as mirror. The main charging transistor and the main discharging transistor are alternately conducted. According to a voltage of the charging-discharging capacitor, the output circuit outputs a clock signal and a control signal. The clock signal is connected to control ends of the auxiliary charging transistor and the auxiliary discharging transistor, and the control signal is connected to control ends of the main charging transistor and the main discharging transistor.
