摘要: An exemplary power supplying and discharging circuit (200) includes a control signal input terminal (21), an output terminal (26), a direct current (DC) power supply (22), a bias resistor (27), a first transistor (23), a second transistor (24), and a third transistor (25). The first transistor includes a base electrode connected to the control signal input terminal, a collector electrode connected to the DC power supply via the bias transistor, and an emitter electrode grounded. The second transistor includes a base electrode connected to the collector electrode of the first transistor, a collector electrode connected to the output terminal, and an emitter electrode grounded. The third transistor includes a gate electrode connected to the collector electrode of the first transistor, a source electrode connected to the DC power supply, and a drain electrode connected to the output terminal.
