Ultra-low-power active filters have received increasing attention in recent years due to emerging applications such as bio-signal sensing and wearable electronic devices, where they are employed in ...

The first part of this series described how data flows through processing steps that create a moving average of stock prices over 65 days. Finite-impulse-response (FIR) filters use the same data-flow ...

Listen to the pop, sizzle, and hum. Look at the bars and wavy lines. These and other characteristics of electromagnetic interference (EMI) are very familiar. RF energy is radiated from a culprit ...

Driving an analog-to-digital converter (ADC) for optimum mixed-signal performance is a design challenge. Figure 1 shows a standard ADC driver circuit. During ADC acquisition time, the sampling ...
