Title: Tuned amplifier
Inventor: OE TADATAKA
IPC: H03F3/191
Filed: 1996-04-18
Granted: 1996-11-21
Abstract: A tuned amplifier includes two phase shifting circuits (10C and 30C) each cascading and an adder comprising a feedback resistor (70) and an input resistor. The phase shifting circuit (10C) includes an operational amplifier (12), a resistor (18) which one side is connected to an inverted input terminal of the operational amplifier (12), a resistor (20) which is connected between the inverted input terminal and an output terminal of the operational amplifier (12), a serial circuit comprising a capacitor (14) and a variable resistor (16), and a voltage divider comprising resistors (21 and 23). An output amplitude of the tuned amplifier is kept up with a prescribed level by making equal each resistance of the resistors (18 and 20), even if the tuned frequency changed. Since the input signal to the voltage divider is leaded to the output terminal of the tuned amplifier, the tuned amplifier can amplify the input signal with the high gain as well as can perform the turning operation. The phase shifting circuit (30C) is comprised in the same manner as the phase shifting circuit (10C). The phase shifting amount of two phase shifting circuits (10C and 30C) is set to 360 degree when the frequency of the input signal is the prescribed frequency and the tuned amplifier (1) performs the tuning operation at the prescribed frequency.
