WebThis circuit demonstrates how to improve the switching speed of BJTs using a speed-up capacitor. Both the turn-on and turn-off times of the BJT are reduced. The speed-up capacitor works as follows: When the input is at low state and the capacitor is fully discharged, the voltage across its plates is 0 V. When the input is switched to high state ... WebHigh Gate capacitances on MOSFETs with high-speed switching means you must have large Gate drivers and very high drive currents to a MOSFET (ex: +/-500mA), as opposed to the low drive currents to a BJT (ex: 50mA). So, faster switching frequencies means more losses in driving the Gate of a MOSFET, as opposed to driving the Base of a BJT.
