To study and analyse Mixers under CMOS Technology



In this paper various mixers are defined for CDMA applications . Using CMOS makes easier for mixers to act on same chip with other digital and analog circuits . The topologies we are defining are dual gate mixers , back gate mixers, single balanced current switching mixers and back end mixers . The back-gate mixer utilizes the inherent lateral bipolar transistor in CMOS. Device simulations were performed to analyze the behavior of the lateral bipolar transistor and extract a madel for it. The characteristic of the transistor were verified through measurements. The mixer circuit only draws 1.3 mW from a 1 V supply . Other mixers are also defined not only to achieve linearity , but also conversion gain and power dissipation.
