This paper presents designing of an op-amp of 10 bit SAR (Successive Approximation Register) ADC with Split DAC structure for medium resolution. Op-amp as an Comparator circuit is designed and ...

Operational amplifiers (op-amps) are almost the perfect amplifiers. As long as you keep a few important details in mind, they will seem perfect. In part 1, I gave a simplified explanation of how an op ...

A low-power switched-capacitor third-order sigma- delta (ΣΔ) modulator suitable for portable sensor systems is described. The architecture uses only one operational amplifier working in a ...
