This is a simple Wide band Instrumentation Amplifier Circuit Diagram. A high performance, wide band instrumentation amplifier includes a main differential amplifier channel which receives an input signal having both differential . Has an input resistance of 1-MO, a bandwidth from de 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-frequency 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 de output voltage.
