Title: Variable gain amplifier
Inventor: MUROI KIYOSHI
IPC: H03G3/30
Filed: 1989-05-26
Abstract: PURPOSE:To avoid the effect onto a post-stage circuit when an input signal is smaller than a preset minimum value by providing a limiter circuit limiting the variable range of a control signal controlling the gain of a variable gain amplifier into a preset range. CONSTITUTION:A limiter circuit 25 controls the lower limit of a voltage of a control signal 16 so that a gain of a variable gain amplifier 21 is not higher than the gain with a minimum input even when the voltage of a control signal 14 is lower than the voltage with a minimum input. In this case, when the input signal 11 is smaller than that with the minimum input, since the gain of the amplifier 21 is limited to the gain with the minimum input, the output signal 12 is smaller than the specified output voltage and the quantity decision signal 13 is kept small, the voltage of the signal 14 is lower up to the state with no signal. Thus, even when the gain of the amplifier 21 is limited to the gain with minimum input, an input interrupt detection circuit 24 is operated. Then a disadvantage that the output signal 12 is amplified till the specified output voltage when the signal 11 is smaller than the voltage with minimum input is avoided.
