Abstract :
This paper presents the design of a high value integrated resistance by analyzing three OTA (operational transconductance amplifier) topologies, and makes a comparison among them. This resistance is used to obtain high time constants in neural signals acquisition systems (NSAS). In order to achieve this goal, the gm/Id methodology was used, as well as CAD tools based on BSIM 3v3 mathematical model, and the design was made with AMS CMOS 0.35 mum technology.
