Sample-and-hold amplifiers sample an analog voltage and hold it until an ADC can digitize it. A perfect sampling circuit holds a voltage until digitizing is complete. Thus, the amplifier’s output is ...
For the sample-and-hold circuit shown in the figure above, determine the largest value of the capacitor that can be used. Use an output impedance for Z1 of 10 Ω, an “on” resistance for Q1 of 10 Ω, an ...
Serial Peripheral Interface (SPI) output driver chips are popular with embedded designers because they provide multiple outputs without using any CPU I/O pins. This article explains how to adapt a ...
