摘要

This paper characterizes experimentally the non-linearity of MOSFET pseudo-resistors and proposes an accurate and simple model to be implemented into SPICE simulators. The work is based in an indirect measure of the resistance, due to its high value. An application example considers the transitory response of a bio signal amplifier that is dependent on the pseudo-resistors situated in its feedback network. The pseudo-resistor's non-linear behavior is used to decrease de undesirable recovering time of the amplifier. An integrated circuit was implemented in IBM 8HP 0.13 μm technology. Experimental measurements were made and compared to the simulation outputs, obtained using the proposed model, showing a good agreement.
