Since the late 1970s, designers have successfully improved the effective resolution and spurious performance of A/D converters by adding dither—uncorrelated noise—to a converter's input and then using ...

Fig 1. In a typical PWM controller in which the active devices are driven by a simple square wave, a Fourier representation of the clock’s frequency spectrum consists of the fundamental switching ...

Sample rates for analog-to-digital converters (ADCs) and digital-to-analog converters (DACs) continue to evolve, now reaching 5 Gsamples/s at 10-bit resolutions and 1.5 Gsamples/s at 12 bits. These ...
