Abstract
The controller of a current-mode buck converter is
realized by only time-domain circuits such as voltage-controlled
oscillator (VCO), voltage-controlled delay line (VCDL), and
phase detector (PD). The inductor current is sensed by a VCO,
which helps improving power efficiency and eliminates the need
for the slope compensation preventing the sub-harmonic oscilla-
tion. The type-II frequency compensation network is realized by a
combination of VCO and VCDL without an error amplifier (EA)
and RC netw
