The PSTB (periodic stability) analysis feature in Cadence Spectre RF Simulation Option performs stability analysis for circuits with periodically time-varying operating points. PSTB is the periodic ...
A regulator is a closed-loop feedback system. For the LDO to be stable, the phase margin must be positive. In other words, at unity gain crossover frequency of the gain curve, the phase of the system ...
Engineers often use SPICE simulations for operational amplifiers to look at the stability of a proposed circuit. SPICE simulations are particularly frequent for high-speed amplifier applications where ...
