Document Type and Number:
WIPO Patent Application WO/2020/075376
Kind Code:
A1
Abstract:
Provided are a power supply circuit and a transmission device with which it is possible to reduce power supply voltages. Provided is a power supply circuit equipped with a current feedback unit, wherein: the current feedback unit has two p-type MOS transistors, a control device, and a first resistance; the two p-type MOS transistors and the control device constitute a current return circuit for returning a current; a current substantially equal to a reference current in the circuit flows in the control device and the first resistance; and the output voltage is determined depending on at least the first resistance and the reference current.
