A 0.9-V Input Discontinuous-Conduction-Mode Boost Converter With CMOS-Control Rectifier

A Dual-Output Thermoelectric Energy Harvesting Interface With 86.6% Peak Efficiency at 30 <inline-formula> <tex-math notation="LaTeX">$\mu {\text {W}}$ </tex-math> </inline-formula> and Total Control Power of 160 nW

“…For the proper operation of the converter and to prevent conduction of body diodes, the driver circuits and the bulk terminals of the pMOS switches of the converter should be powered from the greater of V CT RL and V ST at any time. The supply MUX circuit compares V CT RL and V ST and connects the greater of the two voltages, V M AX , to the corresponding circuits [20]. The supply MUX circuit is shown in Fig.…”

“…The level of the negative output is adjusted so that the switch M 2 is properly turned off. Unlike the supply MUX in [20], this solution does not consume any static power.…”

Design and implementation of PFM mode high efficiency boost regulator

“…PWM mode Boost Regulators operate in fixed frequency operation and are capable to supply higher load with higher efficiency. But at lower load condition, due to the constant switching loss, the efficiency degrades significantly [1][2][3][4][5][6][7]. PFM mode Boost Regulators, on the other hand operate in discontinuous conduction mode (DCM) and hence skip pulses at light load condition [1,8].…”

PWM CMOS DC-DC Boost Converter with Adaptive Dead-Time Control

“…이러한 전력관리 시스템의 효율을 향상시키기 위한 PMIC(Power Management IC)에 대한 연구가 활발히 진행되고 있다 [1][2][3][4][5][6][7][8][9][10][11]. 기존의 DC-DC 부스트 변환기(boost converter)는 전력(power) 스위치 트랜지스터를 구동하기 위해 non-overlapping gate driver를 사용한다.…”

“…이 회로는 두 개의 전력 스위치(NMOS, PMOS)가 동시에 'on'이 되어 효율이 감소하는 구간을 없애기 위해, 둘 다 'off'되는 dead-time 구간을 의도적으로 발생시키는 역할을 한다. 그러나 기존의 non-overlapping gate driver는 dead-time이 고정되어 있기 때문에 body-diode conduction loss 또는 charge-sharing loss가 발생하는 문제점을 가지고 있다 [4].…”
