Title:
差動増幅器
Document Type and Number:
Japanese Patent JP5266156
Kind Code:
B2
Abstract:
A differential amplifier includes first and second current paths, each connected between first and second power supplies (PS) and respectively outputting first and second differential output signals. The first current path includes: first transistor, selectively interconnected between the first PS and a first output terminal, its gate receiving one differential input signal; second transistor, connected between the second PS and the first output terminal, its gate receiving the other differential input signal; and first switch circuit. The second current path includes: third transistor, selectively interconnected between the second PS and a second output terminal, its gate receiving one differential input signal; fourth transistor, connected between the first PS and the second output terminal, its gate receiving the other differential input signal; and second switch circuit. One of the first and second switch circuits is connected to the first PS and the other is connected to the second PS.
