In this tutorial, we will design and simulate a CMOS ring oscillator circuit using BSIM 4 models with the help of LTspice tools. What is a ring oscillator? An odd number of inverters form a closed loop with positive feedback forming a ring oscillator circuit. The oscillation frequency of this CMOS ring oscillator circuit … Read more
How to simulate operational amplifier using LTspice? Before that let us understand about Operational amplifier. Without an Operational amplifier, we can never imagine the current gadget world. The contribution of the Operational amplifier is immense and find use in various technology. Most youths love to party during the weekend, and the question they come across, … Read more
It’s a weekend, and it’s time to go down to the pub and put some random steps on the dance floor to your favorite songs of DJ Snake-Lean on, Magenta Riddim. But have you ever wondered how the DJ controls the music and sound equipment at the night clubs? Ever thought about how the volume … Read more
The Common drain amplifier is a single transistor MOSFET amplifier, one of the basic fundamental MOSFET amplifiers. The Common drain amplifiers are different from Common source amplifiers where the resistor connected across the drain. Let us analyze the input resistance, output resistance, and the gain of the amplifier. Based on these parameters, it provides insight … Read more
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
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
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
