“…The move to higher switching speeds also leads to higher switching frequencies, which therefore requires level shifters with reduced propagation delay, ideally sub-ns [2], [3], and reduced low power dissipation per transition. The combination of low delay and high slew immunity is difficult to achieve, for example the 120 V/ns capable level shifter of [7] has a 20 ns propagation delay.…”

“…In (Ke et al, 2016), a V SW dual-edge DT modulator was designed, which senses load current and supply voltage and then generates modulated delays for V SW rising and falling edges to adjust the instant DT, realizing zero-voltage switching for the GaN power switches. However, this method is too complicated for the CPIOS context of this project and the power consumption of the sub-ns comparator is high, leading to significant power loss.…”

“…In (Ke et al, 2016), an adaptive charging scheme called adaptive bootstrap balancing was proposed. To avoid overcharge, the charging time is initialized until the V SW zero-crossing sensor determines that the charge voltage has enter the safe zone.…”

“…For GaN-based circuits where power-circuit transients are measured in units of nanoseconds, a key specification of these drivers is the rate at which waypoints are processed and output. Most drivers are capable of providing only two [6], [7] or three [8], [9] waypoints during a 10 ns transient. A sub-GHz waypoint rate results in limited waveform shaping capability, but rates greater than 1 GHz are beyond achievable clock speeds in high-voltage CMOS silicon processes that are typically used for gate drivers.…”
