Abstract: PURPOSE:To control a voltage gain over a wide range by providing couples of switching transistors (TR) between a differential amplifier and a programmed resistance network and then turning on and off them selectively. CONSTITUTION:In the circuit diagram of a three-stage gain switching amplifier, when a relatively plus control voltage is applied to a control terminal 1A from a logical circuit, a couple of switching TRs 32a and 32b turn on and the collector differential output currents of differential TRs 12' and -13' is supplied to output terminals 28' and 29' as they are. When the control terminal A is in an active state, current shunting operation is minimum, so the gain is maximum. Then when a control terminal B is held at a relatively high level, a couple of switching TRs 34a and 34b turn on and shunt currents to the output terminals are reduced to obtain an intermediate gain. When a control terminal C is activated, the shunt amount of collector signal currents to the output terminal sides is minimized, so a minimum gain is obtained.
