High-speed integrator circuit (LM101A, LM108)


Posted on Mar 28, 2007

As shown for the high-speed integrating circuit. The integration time constant circuit RtCt have a greater range. If you do not consider integrating capacitor Ct, A2 is a positive feedback compensation broadband AC amplifier. A2 negative feedback loop coupled

capacitance Ct, constitute an integrator. Due to the low frequency and DC portion of the input signal by A1 and A2 of the resistor R2 is added to the same inverting input constitutes a high speed integrator, and may allow smaller input bias current. Positive feedback is compensated by the R4, C4 and C5 constitute. Diodes D1 and D2, D3 and D4 Zener diode and a resistor R5 composed clamp. Two Zener diode should be approximately equal stable voltage.
