<p>The phase shifter has unbalanced input and output, and a voltage divider consisting of a capacitor and resistor. Input voltage is applied to the voltage divider one end, and opposite phase input voltage to its other end. Output voltage is collected from the junction point between the capacitor and resistor. Two amplifiers (V1, V2) are inserted between the input voltage source and the two ends of voltage divider (C, R1). One amplifier (V1) has a positive voltage gain, and the other amplifier (V2) a negative gain, with the gain V being greater than one.</p> |
