Posilive shunt feedback cancels shunt impedance of bitts network and transistor. RE1 is made small to obtain gain of 10; as a result, input impedance is limited to 1.5 meg. Excellent bias stability is obtained. Three diodes compensate for variations in base-emitter voltage of Q1, and negative d.c feedback from RE2 further increases bias stability. Response is flat within 3 db from 100 cps to 500 kc.-Toxas Instruments Inc., Solid-Stale Communications, McGraw-Hill, N.Y., 1966, p 184.
