Has an input resistance of 1-MΩ, a bandwidth from dc to about 35 MHz, and a gain of 10 times. Low-frequency gain is provided by a CA3130 BiMOS op amp operated as a single-supply amplifier. High-fre-quency gain is provided by a 40673 dual-gate MOSFET. The entire amplifier is nulled by shorting the input to ground and adjusting R9 for zero dc output voltage.
