Abstract
PURPOSE: To realize an amplification with a high S/N, by forming several units of FET into a complementary differential amplifying circuit in terms of DC and also securing a parallel connection among those FETs in terms of AC respectively.
CONSTITUTION: The input signal supplied to the terminal 1 is applied to the FETs Q1 and Q2. The AC component of the input signal is applied to the FETs Q3 and Q4 via the capacitor C1 and accordingly amplified by a parallel circuit of FETs Q1∼Q4 to increase the S/N. On the other hand, the DC component of the output signal delivered through the terminal 2 is fed back to the gate of the FETs Q3 and Q4 via the resistance R14. Thus the DC gain of the amplifying circuit can be set to 0, and the quality of sound can be improved in case when the acoustic signal is used for the input.
