ABSTRACT:
A voltage setting circuit includes a voltage setting region setting a voltage level corresponding to a maximum value in amplitude of a signal output from an OTA circuit, a voltage setting region setting a voltage level corresponding to a minimum value in amplitude of the signal, and an intermediate voltage setting region setting a voltage intermediate between the voltages set by the above two regions. This intermediate voltage is input to a common mode feedback circuit and in accordance with the intermediate voltage the common mode feedback circuit generates a common mode voltage fed back to the OTA circuit.
