This circuit idea for hot swap applications uses a regular PNP transistor (TR1) and a current sense/set resistor (R1) to provide continuous current sensing and limiting. As power is applied, current ...

Explains the principles of transistor switching circuits, highlighting their role in electronic computers. It contrasts transistors with vacuum tubes, emphasizing that transistors function as ...

A new technical paper titled “Accelerating OTA Circuit Design: Transistor Sizing Based on a Transformer Model and Precomputed Lookup Tables” was published by University Minnesota and Cadence. Abstract ...

Relay with Multiple Poles/Throws: For complex circuits, several switching contacts can be used, such as SPDT (Single Pole Double Throw) or DPDT. Relay Switch Circuits NPN Relay Switch Circuit When the ...

Figure 2. These LDO examples show how to use (a) low VCEsat NPN-BJT and (b) VCEsat PNP-BJT as pass transistors. Device matching is still relevant In many electronic circuits, the exact values of BJT ...

NPN and PNP Transistor Pulse Outputs: An Open Collector NPN output is configured like a switch to the 0V supply of the flow meter. It requires a ‘Pull-Up’ resistor connected to a positive voltage.

3. Power management PNP transistors are often used in power management circuits, such as low-dropout regulators and high-side switches, while NPN transistors are used in power management circuits that ...

In the early days, PNP bipolar transistors were common, but the bulk of circuits you see today use NPN transistors. As [Aaron Danner] points out, many people think PNP transistors are “backwa… ...

Notice that the function of the gate is the programmable part of the programmable junction transistor. By choosing a voltage for the gate, we can establish the threshold point when the current starts ...

Crazy Tube Circuits has released a limited edition twist on its Unobtanium preamp/overdrive pedal, the amp-in-a-box drive twofer that has a Klon-style drive on one side, and two Dumble tube amp ...
