By applying resonant charge redistribution (RCR) to the parasitic capacitances of a switched-capacitor converter, C OSS -related dynamic switching losses can be significantly reduced. The proposed technique demonstrates adiabatic mitigation of all pr

Here we describe a gate-driver with resonant action that minimizes gating loss at high switching frequencies (10-20 MHz) while facilitating variable voltage gain that can exceed the supply rails. The gate voltage swing can be controlled with minimal
