摘要：
The power supply tuning circuit in accordance with the present invention is provided with a plurality of power supply circuits. Each power supply circuit includes a latch circuit. The latch circuit records a tuning signal. The recorded tuning signal causes the corresponding transistor to switch on/off. In this manner, pseudo-tuning is performed. After a tuning signal is supplied to the latch circuit, the tuning signal is supplied to another power-supply circuit. Thus, pseudo-tuning can be preformed simultaneously for a plurality of power supply circuits.
