The recent Design Idea “Getting an audio signal with a THD < 0.0002% made easy” discloses a low THD sine generator which led me to dust off a design...
A simple, purely analog -130 dB THD sine wave generator
TI introduces the world's smallest MCU, enabling innovation in the tiniest of applications
Texas Instruments introduced the world's smallest MCU, expanding its comprehensive Arm Cortex-M0+ MSPM0 MCU portfolio. Measuring only 1.38 mm2, about the size of a black pepper flake...
Three discretes suffice to interface PWM to switching regulators
It’s remarkable how many switching regulator chips use the same basic two-resistor network for output voltage programming...
Single-supply single-ended input to pseudo class A/B differential output amp
From the micromixer topology by Barrie Gilbert, this amplifier allows a single-ended input to be converted to a Class A/B current output from a single supply...
The Internet formed in the 1960s - How did it start?
Initially imagined by Nikola Tesla in the early 1900s, the concept of a world wide web didn’t see creation until 60 years later. Take a trip alongside the history of the internet...
1 A, 20V PWM DAC current source with tracking preregulator
This design idea reprises another “1 A, 20 V, PWM controlled current source”. Like the earlier circuit, this design integrates an LM3x7 adjustable regulator with a PWM DAC to make a programmable 20 V, 1 A current source...
STMicroelectronics releases innovative satellite navigation receiver to democratize precise positioning for automotive and industrial applications
STMicroelectronics has introduced the Teseo VI family of global navigation satellite system receivers aimed at high-volume precise positioning use cases...
Simple setup tests bit-error rate
Traditionally, the reception quality of a digital receiver is expressed in terms of BER. This figure is the proportion of received bit errors in a given period...
Regulation loop without a resistive divider
A new control loop architecture is designed to generate very low noise voltages. This can be utilized by both linear and switching regulators...
Design an RTD interface with a spreadsheet
RTDs are the preferred sensor choices for designs requiring precision. Although RTDs are approximately linear over the limited temperature range of 0 to 100 °C, these sensors exhibit a slight but progressively more nonlinear temperature-versus-resistance characteristic as the measurement range widens...
