Looking for a massive current boost in your analogue circuit designs?

The Darlington Pair configuration is an incredibly elegant solution when a single bipolar transistor just can't deliver the gain you need to drive low-impedance or high-current loads.

By cascading two transistors—connecting the emitter of the first directly to the base of the second—the total current gain (hFE) becomes the product of the two individual gains:

If you pair two modest transistors with a gain of 50 each, you instantly achieve an overall current gain of 2,500!

Key Advantages:
* Ultra-high current gain: Ideal for power supplies, audio output stages, and display drivers.
* High input impedance: Minimises loading effects on the preceding circuit stages.
* Design flexibility: Available as single integrated components (like standard Darlington transistors or IC arrays) or easily built with discrete components.

Design Considerations & Trade-offs:
No circuit is perfect, and the Darlington configuration comes with specific trade-offs:
* Higher VBE drop: Because you are driving two base-emitter junctions in series, you need around 1.2V to 1.4V (for silicon) to turn the pair on.
* Higher saturation voltage: Typically around 0.7V, which can increase power dissipation in switching applications.
* Slower switching speeds: The output transistor can be slow to turn off because its base charge has no quick path to dissipate.

Pro-Tip: To combat slow turn-off times, it's good practice to include a base-emitter bypass resistor across the second transistor to help discharge that stored junction charge faster!

TinyGPU v3.0 is coming with a programmable Pixel Shader!!
Tested on FPGA and submitted to the #TinyTapeout May shuttle (~290k transistors).
This Chameleon demo is a tribute to the #GeForce 3, the first programmable GPU released 25 years ago. https://t.co/GCy7tmGfUA

@fishPointer You need a jewelry laser welder. Great for spot welding tasks. Seriously figure out how to try one out. They are almost magical in a lab when you are building small assemblies.

The single biggest hidden enabler of this jump isn’t the laser power scaling (which everyone expects) — it’s a new tin droplet pre-pulse shaping technique we’ve been quietly validating since Q3 2025.
