RECEIVE AMPLIFY CIRCUITS

摘要

This circuit for receiving amplifier comprises a protection circuit (10), a transmission gate (20), a bias circuit (30), an input amplifier circuit (40) and a storage circuit (50). The protection circuit can protect the circuit of receiving amplifier from the input signal. The transmission gate executes an operation that an output potential is not affected by the extrnal noises. The bias circuit supplies constant current. The input amplifier circuit amplifies a receiving input signal.
