Item type:Publication, Access status: without files , A 130nm CMOS programmable operational amplifierIn this work we present a programmable 1.2 V Operational Amplifier (OpAmp) realized in a standard 130 nm CMOS technology. The OpAmp is based on a 3 V rail-to-rail input/output topology. The experimental results show the feasibility of using higher voltage topologies in conjunction with multi-threshold (multi-Vth) process options for low voltage designs. The programming range extends from a low-noise to a low-power mode. In addition, a constant-gm stage has been added to the rail-to-rail input. In low-noise mode the OpAmp has a low input thermal noise voltage of 5.1 nV/√Hz and in lowpower mode a power consumption of only 203 μW. Over the whole programming range the OpAmp maintains unity-gain stability with its phase margin varying between 58° and 62°Publicationtype: Conference Paper15 - Some of the metrics are blocked by yourconsent settings
Item type:Publication, Access status: without files , Analog circuit calibration with single poly non-volatile memories(IEEE, 2008-11); ; ; A single poly non-volatile memory module for analog circuit calibration fabricated in a standard 350 nm CMOS process is presented. This module performs the read, program and verify operations for non-volatile storage applications. This circuitry can be used, e.g. for storing data to individually adjust sensitive device parameters of biomedical analog front ends to meet precisely the target specifications. The module can be embedded in analog or mixed signal chips based on 350 nm CMOS technology.Publicationtype: Conference Paper6
