Designed for use in implanted transmitters monitoring brain and heart potentials. Requires only 4μA at 1.35 V.Voltage gain is 2000, and equivalent input noise only 10 μV P-P with 10-megohm source impedance. Tr1 is current-starved, but resulting limited bandwidth of about 5 kHz is acceptable for biological applications.-C. Horwitz, Micropower Low-Noise Amplifier, Wireless World, Dee. 1974, p 504.
