Semiconductor circuit device capable of reducing influence of a parasitic capacitor

摘要

A semiconductor circuit device includes a differential amplifier circuit having a first parasitic capacitor formed between the semiconductor substrate and a first resistor and a second parasitic capacitor formed between the semiconductor substrate and a second resistor. Each of the first and the second resistors is implemented by a wiring pattern over the substrate so that the first and the second parasitic capacitors are equivalent to each other.
