关于boostraped switch在低压下
In order to reduce distortion due to variation of the gate
overdrive and the threshold voltage, a novel low-voltage constantresistance
sampling switch is proposed in this paper. The technique
to reduce nonlinearity can be used in a high resolution sample and
hold circuit. TSMC 0.18um standard CMOS technology is utilized
in this research. Results indicate that much lower Total Harmonic
Distortion (THD) is achieved by the proposed circuit. The low
THD meets the requirements in the application of the low-voltage
low-distortion switched-capacitor circuits. |
