Title:
電流出力回路および無線通信装置
Document Type and Number:
Japanese Patent JP5933466
Kind Code:
B2
Abstract:
A current output circuit includes a current mirror circuit that has first and second transistors in each of which a source is connected to a reference voltage, and that outputs a current which is proportional to a drain current of the first transistor, from a drain of the second transistor; a switch that turns ON/OFF the current output of the current mirror circuit; a third transistor in which a gate is connected to a gate of the second transistor; and a bias circuit that applies a first voltage to a drain of the third transistor. The bias circuit switches the first voltage to two different voltages in synchronization with opening/closing of the switch.
