Design of CMOS Four-Quadrant Gilbert Cell Multiplier Circuits in Weak and Moderate Inversion
… multiplier architectures based on the bipolar Gilbert cell multiplier architecture. Multipliers are designed using the CMOS subthreshold region to take advantage of the subthreshold exponential I-V relationship that closely matches bipolar modeling. It is discovered that biasing to remove drift …

Advanced Downconversion Mixers for CMOS Radio Frequency Integrated Circuits
… As it generates the low-frequency IM3 for the cancellation fully in the IF band, the technique can bring third-order input intercept point (IIP3) of the mixer that is robust against parasitic parameters and process variations. Furthermore, this method can be applied to any active mixers regardless …

V-band low noise amplifier and mixer design using 90 nm CMOS technology
… low noise amplifier and a fully differential Gilbert cell with resonating current bleeding network have been chosen for being part of the WiONet system. Both circuits showed state of the art performance in terms of gain, linearity, noise and power consumption. Furthermore, they fulfil the …

Low-Power RF Front-End Design for Wireless Body Area Networks
… isolation. The up-conversion mixer is based on a Gilbert cell with resistive loads. Simulation results and performance comparisons for each designed building block are presented. Finally, we present a case study on a direct VCO modulation transmitter and a super-regenerative receiver, which can …
