ABSTRACT:
An output circuit whose outputting signals having large voltage swing by using switches with low voltage tolerance is provided. The output circuit includes: operation amplifiers, receiving positive input voltage and negative input voltages, respectively; transmission gates, passing output signals from the operation amplifiers, respectively; switch transistors, passing output signals from the transmission gates as an output signal of the output circuit, pulling up the output signal from one of the transmission gates, and pulling down the output signal from the other of the transmission gates.
