Abstract
Embodiments disclosed herein relate to synchronous boost converters, and to feedback based zero current detection (ZCD) circuits and operation methods for precisely detecting zero current crossing. The feedback based ZCD circuit may improve power efficiency of a fully on-chip, high gain, and high frequency synchronous boost converter by preventing generation of reverse inductor current in a dead phase of synchronous boost converter. The feedback based ZCD circuit may be a comparator based ZCD circuit for obtaining a precise Discontinuous Conduction Mode (DCM) operation with high efficiency. The feedback based ZCD circuit may be a voltage controlled delay line (VCDL) based ZCD circuit for obtaining a precise DCM operation with high efficiency. The feedback based ZCD circuit may generate a feedback control signal for a switch for accurate and adaptive turning off at all dynamic conditions of various circuits.
