Two diodes and two zeners clamp output of integrator below saturation level of opamp, making recovery time approximately equal to slew rate. With values shown, integration time constant R3 C1 is 35.6 ms and output is clamped at +23 V. Output linearity is ±1%, and threshold range of circuit is -3 V to -10 V.-K. S. Wong, Fast-Recovery Integrator with Adjustable Threshold,EEE Magazine, Aug, 1970, p77.
