Abstract
The implementation of the mixer-first FSK receiver given in the previous chapters is presented in this chapter. Special attention is paid to the passive mixer and first IF amplifier since they determine the noise figure of the complete receiver. The feasibility of a low-power mixer-first receiver with free-running ring oscillator is studied. A radar plot is used to compare the presented receiver with other reported low-power FSK receivers, since the specific receiver optimization target can be seen immediately, e.g. low-power consumption, high linearity, etc. The chapter ends with conclusions and presents recommendations for future low-power front-end designs.
