Simple Circuit Overcomes MOSFET Gate-Threshold Voltage Challenge Dec. 17, 2014 When a MOSFET or IGBT gate-threshold voltage is higher than the available drive voltage, it's standard to use an op ...

The reference frequency in this circuit drives the input of an exclusive-OR gate (XOR gate U2) as well as the input to a delay circuit. Consisting of R1, C1, and comparator U1, the delay circuit ...

There are plenty of simple SSR circuits available, but this may be the simplest circuit that achieves turn-on and turn-off only when the AC line voltage is near zero. Figure 1 AC SSR schematic with ...

Often, designers add series resistor R9 as a tool to measure and verify stability of the feedback loop. In production, this may be replaced with a zero Ohm resistor. The open circuit protection ...

For the past several years, researchers have been creating living logic gates, using the genetic on and off switches we've discovered in the biochemical world to create simple logical functions.
