Common Source Amplifier Circuit simulation using LTSpice

A design engineer can design an op-amp using the passive components, what is the need of MOSFET based single-stage amplifiers? MOSFET transistors, have an edge over passive components, they can save the chip area. MOSFET, an active device, can produce higher resistance compared to passive load, which would result in higher gains. Common source amplifier … Read more

DC Characteristics of CMOS Inverter using LTSpice circuit simulation

In this tutorial, we will simulate the CMOS Inverter using LTSpice XVIII circuit simulation tool. In this CMOS inverter circuit simulation, we will use the BSIM4 Spice model. What is BSIM4? That might be your next question. BSIM came into prominence during 1987, known as the Berkeley short-channel IGFET model. Modeling of any device involves … Read more

Simulation of Ideal Operational Amplifier using LTspice.

Our second tutorial will focus on simulating an ideal op-amp, using the LTspice simulation tool. But what is an ideal op-amp? The figure below shows an ideal op-amp, the input impedance is denoted, as Rin and does not allow any current to flow into it. Ideally, the op-amp input impedance must be infinite, and the … Read more

LTspice simulation tutorial on voltage divider

Any circuit design engineer before developing a circuit would like to simulate that circuit to understand whether it satisfies the design rules, and this also gives an option of plug, and play which is not possible practically. To design and develop a circuit with no parts cost and circuit can be evaluated without any physical … Read more
