Abstract
PURPOSE: To keep current balance of a differential pair transistor (TR), by connecting the collector of one TR of a differential pair TRs of the 1st stage differential amplifying circuit to a specified power supply terminal and flowing a half the current of the constant current source to the collector of another TR of the differential pair TRs.
CONSTITUTION: If the balancing of differential pair TRs Q3, Q4 is taken, the same base current IB flows respectively. A current I+IB flows to the 2nd TRQ2, where the I is a current flows to each path of the 2nd current Miller circuit 24, and a current I+IB flows to the 2nd path of the 1st current Miller circuit 23. Thus, the current I+IB flows also to the 3rd and 4th paths of the circuit 23 and a current 2(I+IB) flows to a common emitter connection circuit of the differential pair TRs Q1, Q2. Thus, entirely equal current flows to the differential pair TRs Q1, Q2 to keep good current balance.
