P-channel fet is combined with pnp transistor in equivalent to Darlington connection, for use with high-input-impedance low-frequency transducers.Spot noise figure is 7 db at 10 cps and 3 db at 100 cps. Broadband noise figure from10 cps to 10 kc is 1.7 db with 200K generator resistance.-Texas Instruments Inc., Solid-State Communications, McGraw-Hill, N.Y., 1966, p 136.
