Patent DE-19723248-A1 (DE)
Title: Self=regulating amplifier circuit with amplification factor control
Inventor: AOYAMA SEIKI
IPC: G01P21/02
Filed: 1997-06-03
Abstract: The amplifier processes input AC signals, and the circuit contains a comparator circuit (7, 8) for examining the amplifier (3) output signal with respect to upper and lower reference limit values.  An upper limit signal (CMP/U) is delivered, when the amplifier output signal exceeds the upper reference limit value, while a lower limit signal (CMP/D) is transmitted when the output signal is below the lower reference limit value.  The amplification change is determined by an amplification factor control determining circuit, which responds to the comparator circuit.  The control circuit selectively short circuits terminals on either side of each resistor for changing overall resistance, in order to control the nett amplifier gain.
