An almost rail-to-rail full clock fully differential rectifier and sample-and-hold amplifier is presented. It is based on a class AB fully differential two stage amplifier. It uses the miller compensation capacitor to hold the output and a duplicate of the output stage to ensure offset cancellation and proper common mode control. Simulation results, in 0.35 μm CMOS technology, show power consumption...
A low-power low-voltage rectification and sample-and-hold circuit is presented. The circuit is based on transistors operating on weak inversion using a procedure developed in this paper. The proposed circuit can be programmed to function as sample-and-hold only or rectification and sample-and-hold. The design has been simulated with the CMOS 0.35 ??m, 3.3 V technology. For a power supply voltage of...
A 10 MHz, low-power, high-accuracy fully- differential always-valid sample-and-hold (AVSH) circuit is described. The circuit is based on the high dc gain Miller compensation operational amplifier. Its low- power make it suitable for biomedical application such that implantable smart medical devices (SMDs). The proposed circuit has been designed with CMOS 0.13 mum technology. The simulation shows that...
