Single-MOSFET circuits gate & modulate

Discrete small-signal MOSFETs still find uses today, and this Design Idea presents two simple examples: an AND gate, and an amplitude modulator. Figure 1 shows a standard two-input AND gate along with ...

RFL-class logic gates

This Design Idea describes a new class of logic gates, which we have named resistor-FET-logic, aka “RFL.” How do we know it is new? While FET switches are common today, we have been unable to find a ...

MOSFET Synchronous Rectifiers Require Attention to Gate Charge

The switching speed of a power MOSFET charge-controlled device depends on the speed with which an associated gate driver circuit can charge its input capacitance. For the last 20 years, many excellent ...

Simple Circuit Overcomes MOSFET Gate-Threshold Voltage Challenge

This file type includes high resolution graphics and schematics when applicable. In some situations, it becomes necessary to drive a MOSFET (or IGBT) with a voltage that’s lower than its ...
