Abstract: “This paper presents a sample-and-hold circuit based on a cascode-miller compensation technique, utilizing a class-AB operational amplifier as an output stage. Also using the techniques of pre-charging and output capacitor coupling can mitigate the requirements for the op-amp, resulting in low power dissipation. Power consumption is about 300µW from a single 1-V power supply. The performance of this SHA is not degraded even if input frequency approaching up to Nyquist frequency.”
