Abstract

An RF mixer is one of the key elements in wireless telecommunication systems, which is used for example for modulation and demodulation. Due to the fact, that such a functionality can only be achieved by a nonlinear system, it is crucial that the nonlinearity is taken into account for the analysis and design of RF mixers. For this reason, the analysis and design process is still a challenging task because linear models can only be used restrictively. Therefore, an iterative design process is performed to achieve the desired specifications, whereby a circuit simulation tool as Cadence Spectre is utilized for verification. This approach is very time consuming as a vast of numerical simulations have to be performed for each set of network parameters. In this contribution, another approach is presented based on a self-consistent Carleman linearization. This approach is used to obtain an approximate analytic solution in dependency of the network parameters.
