Tag: Phase Shifter

The schematic diagram below shows a variable 0-180 degree phase shifter circuit. This circuit can provide  phase shifted output (compared with the input) between 0 and 180 degrees for frequencies up to 3MHz with same amplitude (unity gain or gain=1.) This circuit uses inexpensive NPN transistor, 2N3904, but almost any small signal transistor type can be used. Using R5 and […]

This a 0 to 360 shifter circuit. This circuit consist of two stage phase shifter which each of them provides 0 to 180 phase shift. This circuit uses the 2N3070 JFETs because the phase shift networks are not loaded by them. Here is the circuit : [Source: National Semiconductor Application Note]
