Bias circuits for class AB buffers don't have to ruin your total harmonic distortion spec. Here's some tips on how to prevent the bias circuit from influencing the amplified signal ...

A sine wave generator that achieves a THD of better than 130 dB below the fundamental output offering both simplicity and performance.

If a circuit produced a perfect sine wave, there would be no harmonics. There are many ways to measure THD in practice, but [Michael Jackson] has an interesting video showing how he easily ...

A novel scheme of total harmonic distortion (THD) adjustment for light-emitting diode (LED) alternating current (AC) direct driver integrated circuit (IC) is presented. The current flowing through the ...

A circuit using STM32 chip as the main control is designed to address the issue of semiconductor laser performance being easily affected by injection current and operating temperature. It can achieve ...

The NGD digital circuit theory, operation principle and design methodology are established by means of frequency-time diagram and verified by both simulation and experiment. Various arbitrary waveform ...
