Abstract [en]

This paper presents a 1-V 10bit 50MSPS Switched-Opamp (SO) S/H circuit, designed in 3.3V/1.8V 0.18μm 1P6M CMOS technology, which could be used in wideband wireless transceivers. A new architecture of the low voltage switchable opamp with improved common-mode feed back (CMFB) loop is introduced for its fast wake-up speed. Simulation results show the S/H circuit achieves a THD of -75dB and a SFDR of 76dB at the Nyquist frequency (Fin = F s/2). The opamp only dissipates a static power of 1.9mW even in active phase.
