Filed: 1988-12-15
Abstract: PURPOSE: To cancel an offset effect and educe a noise by composing an input stage of two transistors(TR) which have their bases connected through a corresponding input resistor, supplying an input signal to an audio amplifier by a 1st TR, and adopting a diode constitution to a 2nd TR. CONSTITUTION: The offset voltage of the input to the audio amplifier 1 is given as the product of base currents 11 and 12 of TRs T1 and T2 and corresponding input resistance Rin1 and Rin2. Therefore, the values are equalized, i.e., when Rin1=Rin2 to cancel the offset effect. The TR T2 has the diode constitution through a connection 5 and functions as the ground of a voltage source Vin. The signal input impedance of the audio amplifier is the sum of the input resistance Rin1, the reciprocal of the mutual conductance gm of the TR T2, and the parallel resistance of the resistors R1 and R2. The latter two can be ignored as compared with Rin1, and the input impedance is nearly only Rin1. Noise voltages generated by those resistors Rin1 and Rin2 are filtered so that they are grounded by the capacitor Cin, thereby making none of its appear in the output.
