Abstract:
1. A differential amplifier circuit comprising: a first input terminal and a second input terminal; a first output terminal and a second output terminal; a first P-type transistor having its source connected to said first input terminal, its drain connected to said first output terminal and its gate connected to said second output terminal; a second P-type transistor having its source connected to said second input terminal, its drain connected to said second output terminal and its gate connected to said first output terminal; a first N-type transistor having its source grounded, its drain connected to said first output terminal and its gate applied with a first potential; and a second N-type transistor having its source grounded, its drain connected to said second output terminal and its gate applied with said first potential, said first potential turning on said first N-type transistor and said second N-type transistor.
