An ultra-low-noise buck converter for noise-sensitive applications is presented, which utilizes a novel pseudo average current-mode control (ACMC) with an adaptive ramp generator to decrease the baseband noise. Also, in order suppress electromagnetic interference (EMI) and high-frequency spurs, spread spectrum secondary filter are used, respectively. The proposed ACMC suppresses switching frequency perturbation effect on output voltage, as result condition, only small amount of noise added...
