“Gold-plated” without the gold plating Alright, I admit that the title is a bit over the top. So, what do I mean by it? I mean that: The application of PWM control to a regulator does not significantly degrade the inherent DC accuracy ...
A simple current source It has long been known that the simple combination of a depletion-mode MOSFET (and before these were available, a JFET) and a resistor made a simple, serviceable current source such as that seen on the right side of Figure ...
A classic nonlinear analog function is the squaring circuit. It’s useful in power sensing, frequency multiplication, RMS computation, and many other odd jobs around the lab bench. Figure 1. The squaring amplifier that is fast, ...
This project made me feel a kind of kinship with Diogenes, although I was searching for the item described in the title rather than for an honest man. Figure 1. “Diogenes Looking for an Honest Man,” a painting attributed to Johann ...
The Norton amplifier topology brings back the essence of analog design by using clever circuit techniques to deliver strong performance with minimal components. It is not about a brand name it’s about a timeless analog philosophy that ...
“Facts are stubborn things” (John Adams, et al). I added two 50-ohm outputs to the schematic of my published voltage-to-frequency converter (VFC) circuit [ 1 ] (Figure 1). Then, I designed a PCB, purchased the (mostly) surface-mount ...
Single Positive-Edge-Triggered D-Type Flip-Flop With Clear and Preset This single positive-edge-triggered D-type flip-flop is designed for 1.65-V to 5.5-V V CC operation. NanoFree package technology is a major breakthrough in IC packaging concepts, ...
