- A simple, purely analog -130 dB THD sine wave generatorThe recent Design Idea “Getting an audio signal with a THD < 0.0002% made easy” [1] discloses a low THD sine generator which led me to dust off a design that I had published in AudioXpress...Mar 7, 2025
- A class of programmable rheostatsBasic programmable rheostats For many variable resistor (rheostat) applications, one of the device’s terminals is connected to a voltage source VS. Such a source might be a reference DC voltage, an op amp...Feb 24, 2025
- Non-linear pullup for multi-rate I2C busesI2C is a popular bidirectional serial communications bus having a clock and a data line. Both line’s drivers consist of an open drain ground-referenced N-channel MOSFET with a pullup resistor connected to a supply...May 13, 2024
- Simple Technique Drives Multiple LEDs From One Processor PinDriving multiple LEDs with one microprocessor GPIO pin is a well-known technique. Typically, designs perform this task by issuing pulse widths and clocks of differing durations and employing multiple RC networks to...May 19, 2021
