Survey and Benchmark of Fully Integrated Switching Power Converters: Switched-Capacitor Versus Inductive Approach

An efficient boost converter control for thermoelectric energy harvesting

“…external inductor is the only topology that can maintain high efficiency at a very high voltage conversion ratio and a wide range of ratios at the same time [5]. The boost converter which is used to validate the proposed control circuit is shown in Fig.…”

“…The delay is controlled by switch ON resistances and it has the largest value when all the switches are turned-off. Switches are sized such that each one of them is reducing the delay according to (5), when it is ON. The input inverter is sized to have negligible ON resistance compared to switches.…”

High speed DC-DC dead time architecture

“…One of the challenges in fully integrated, high speed DC-DC converters is to achieve correct dead time between driving signals [1,2]. The dead time is necessary to prevent losses due to short circuit path and to avoid body diode conduction.…”

“…After selecting V DDN and V SSP , the cascode transistors (M 1 -M 2 and M 3 -M 4 ) and the drivers can be sized to minimize the sum of switching and conduction losses [1]. …”

A reliability improved synchronous boost converter with spike suppression circuit

“…Secondly, the main power MOSFET and the synchronous switch should be avoided to operate in ON state simultaneously because that the shoot-through current between two power switches will ruin the converter. So, a dead-time [2,3] is inserted to the gate control signals. In order to improve the efficiency, various literatures are reported to optimize the dead-time [4,5,6,7,8,9,10].…”
