SCHMITT TRIGGER

Picture courtesy : google Schmitt trigger is an electronic circuit with positive feedback which converts a sinusoidal or any analog signal to digital signal. Schmitt trigger is a comparator circuit with hysteresis, that is the output transition from high to low and low to high will occur at different thresholds. Schmitt trigger belongs to the …

Operational amplifier and Opto-electronic devices

Operatinal amplifier Operatinal amplifier or OPAMP are basic element in an analogue¬† circuit. Opamp is a linear device. When signal is applied to minus terminal of opamp then output is in opposite phase of input. Differential gain of opamp should be greater than common mode gain. Ideal value of common mode rejection ratio CMMR is …
