The small signal analysis of power converters reveals the presence of poles and zeros in the transfer functions of interest (e.g., the control to the output variable). The zeros occur in the numerator ...

The performance of a switching regulator for the given external passive components is largely determined by how well the closed loop is being compensated. An excellent loop-compensation design is ...

The first installment of this article series discussed the need to verify SPICE model accuracy and how to measure the open- and closed-loop small-signal AC output impedance of operational amplifier ...
