Abstract :
A modified envelope-following method for simulation of clocked analog circuits is described. The modification makes the envelope-following algorithm more efficient, as unnecessary numerical integration is avoided when computing the envelope of ´quasi-algebraic´ components in the solution vector. An automatic method for determining the quasi-algebraic solution components is described, and experimental results are given which demonstrate that this modified method reduces the number of computer clock cycles needed to accurately determine the envelope.<>
