Op-amps are incredibly versatile tools used mainly in analog electronics circuits. I have written about op-amps and their applications in filter design, amplifier etc. Here I wanted to write a note on op-amp based Schmitt trigger circuit. While we …
While revising negative feedback amplifiers after long time I noticed that in transimpedance amplifier (also called Current Controlled Voltage Source ) and current amplifier, a source of constant current is required and I did not know what that me…
In differential amplifier design, achieving high Common-Mode Rejection Ratio (CMRR) and maximizing voltage gain are essential goals for optimal performance. The CMRR is a key factor in rejecting unwanted common-mode signals and improving the am…
Differential amplifier can be built using both discrete components such as transistor, resistors, diodes or it can be build using operational amplifier(op-amp). The differential amplifier with discrete components are basic building blocks that toge…
Automatic Gain Control (AGC) is a technique used in audio circuits to automatically adjust the amplitude of an audio signal in real-time, ensuring that the output level stays within a desired range regardless of the variations in the input signal. …
Yesterday I wrote about how a switchable op-amp based signal inverter can be built. It can also be called a phase shifter circuit because the output signal is 180 degree out of phase w.r.t the input signal. The design of actual phase shifter circui…
This circuit is designed with an operational amplifier (op-amp) and a switch, allowing the signal phase to either be inverted or remain unchanged as it passes through the circuit. In other words, the output signal can be 180 degrees out of phase wit…
An operational amplifier (op-amp) integrator circuit is essential in analog signal processing applications such as waveform generation, analog computation, and filtering. In this post, we will walk through the design calculation of a practical op-am…
