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, the authors are defining are dual gate mixers, back gate mixers, single balanced current switching mixers and back end mixers. The backgate 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 model for it. The characteristic of the transistor were verified through measurements.
