摘要： In a signal output circuit, an input buffer externally receives a single-phase switching instruction signal to switch a state of the output circuit a shutdown disable state or a shutdown enable state, and converts and outputs the single-phase switching instruction signal into a differential switching instruction signal. A generation control circuit outputs a generation control signal for controlling generation of a control voltage in the control voltage generation circuit based on the differential switching instruction signal. A control voltage generation circuit outputs the control voltage upon changing a value of the control voltage in accordance with a logic of the single-phase switching instruction signal. An output circuit externally receives a differential input signal, outputs a differential output signal upon impedance-converting the differential input signal, and switches between the shutdown disable state and the shutdown enable state of the differential input signal.

摘要： In an automatic gain control circuit, a peak detection circuit detects and outputs the peak voltage of an output signal from a variable gain circuit. An average value detection/output amplitude setting circuit detects the average value voltage of an output signal from the variable gain circuit, and outputs a calculated voltage. An amplification circuit controls the gain of the variable gain circuit by amplifying the difference between the output voltages of the peak detection circuit and average value detection/output amplitude setting circuit. The number of base-emitter junctions of transistors on a path in the peak detection circuit from input ports which receive output signals from the variable gain circuit to an output port which outputs a voltage to the amplification circuit is equal to the number of base-emitter junctions of transistors on a path in the average value detection/output amplitude setting circuit.
