Spice is a circuit simulator that you should have in your toolbox. While a simulator can’t tell you everything, it will often give you valuable insight into the way your circuit behaves, before you’ve ...

This article describes how LTspice simulations can be used to account for the effect of voltage dependence, or dc bias, caused by the use of ceramic capacitors with smaller and smaller case sizes.

LTspice is a free version of spice from Linear Technology, and it is delightfully easy to use, intuative, and seems to work rather well. Note, there is a flasher version 3 Current through component ...

As a service to our readers, we're providing the LTspice files used in Dr. Dyer's article on simulation of the 12AX7 and the K2-W vacuum-tube op amp. 1. The model for the K2-W is established as a ...

I was testing a circuit and found many discrepancies from the paper design I used to create it. The dynamics of the circuit were a bit unexpected, andthe noise level was much larger than required. I ...
