Voltage-controlled oscillator-based analog-to-digital converters (VCO-based ADCs) represent an emerging class of digitisation circuits that harness the frequency-modulating properties of VCOs to ...

这是一个基于TDA7052A音频放大器芯片的功率电压控制振荡器（VCO）设计，该电路能够产生5倍频程的线性近似音高输出··· 几个月前，技术实例栏目的常客Nick Cornford向我们展示了一些巧妙的电路，这些电路使用TDA7052A音频放大器作为功率振荡器。他的设计也 ...

Fig 1. Two analog multipliers form a VCO with quadrature outputs, while a third multiplier provides AGC to stabilize output voltages without adding distortion. Fig 2. The oscilloscope trace of the VCO ...

Making sound with digital logic usually calls for a Digital to Analog converter. Building one can be very simple, and the sound quality out of an R-2R Ladder is actually pretty good. In the last ...

The project was a signal generator that featured a swept RF output that could go from 1 MHz to 40 MHz. We had no way to make a single sweepable signal source that could cover a 40-to-1 range of ...

Radiation-hardened phase-locked loop (PLL) circuits represent a critical advancement in safeguarding electronic systems against the deleterious effects of ionising radiation. These circuits are ...

The 555 frequency can be varied via adjusting the voltage at pin 5. However, the range and linearity of frequency adjustment is very limited. This is a way to greatly improve performance using the ...

Clock speed is equivalent to data movement in applications that receive and process hundreds of megabytes of data each second. Applications involved in moving enormous volumes of data include cellular ...
