Bias circuit with a replica circuit for an amplifier circuit and a generation circuit supplying bias voltage to the replica and amplifier circuits and optical receiver

A bias circuit includes a replica circuit for an amplifier circuit using a cascode type inverter, and a generation circuit that generates a bias voltage that causes a drain voltage of an input stage transistor of the amplifier circuit to be a saturation drain voltage, based on an output voltage of t...

Zusammenfassung:A bias circuit includes a replica circuit for an amplifier circuit using a cascode type inverter, and a generation circuit that generates a bias voltage that causes a drain voltage of an input stage transistor of the amplifier circuit to be a saturation drain voltage, based on an output voltage of the replica circuit, and supplies the generated bias voltage to a cascode element of the amplifier circuit and a cascode element of the replica circuit.
