Abstract
State-space averaging and perturbation analysis is systematically applied to compute the open-loop and closed-loop transfer matrices (Tol and Tcl) of switching converters working in continuous conduction mode. The power supply rejection function, input impedance and output impedance can be read off directly from Tcl. A circuit-level simulation method, the frequency-point spectrum simulation, is proposed that resembles the actual spectrum measurement procedure to verify the analytical results.
