Abstract
A compact and energy-efficient hysteretic boost converter with an anti-phase AC-coupling emulate current control is presented. The scheme proposes a two-transistor current emulator and a comparator for both fast transient responses and tight closed-loop regulations. Fabricated in a 180 nm CMOS process, the converter regulates a 5 V output with 400 mA load capability from an input between 2.7 V and 4.5V. Measurement results show that the proposed scheme achieved superior transient responses and improved regulation performances. With load transitions between 0 mA and 300 mA, the converter shows over-/undershoot voltages of 38 mV and -42 mV, respectively. The measured load and line regulation performances are 5 mV/A and 2.3 mV/V, respectively.
