Circuits By Ramakant Gayakwad Pdf 124: Op Amp And Linear Integrated

The hysteresis width is then (V_H = 2V_sat \cdot \fracR_2R_1 + R_2). By choosing the ratio (R_2/(R_1+R_2)), the designer can control the noise immunity.

. This is the unsung hero of the modern world. In an era of "noisy" electronics, the op-amp’s ability to reject common-mode noise (interference that hits both inputs) and amplify only the difference The hysteresis width is then (V_H = 2V_sat
