A reliable ultra low power merged LNA and Mixer design for medical implant communication services

CMOS upconversion mixer with filterless carrier feedthrough cancelation and output power tuning

“…Nevertheless, it is important to mention that no de-embedding was applied to the measured data, and hence, losses introduced by the experimental set up are present, which may explain the difference between the measured conversion factor (−55 dB) and the theoretical number (−3 dB). Regarding power consumption, the number is not so good if we look at the ultra low power mixer of [26]. Yet, the UCM design suggested in the current work for the MICS was just a circuit implementation example, and design aspects for dropping the consumption were not made.…”

Design and simulation of novel amplifier‐based mixer for ISM band wireless applications

“…Several techniques have been reported to decrease the supply voltage and the power consumption of the mixers, such as folded technique and current reuse technique . In the folded technique, the RF stage is separated from the LO stage, which reduces the number of stacked transistors, and the supply voltage is decreased.…”

Low Voltage Low Power Folded Mixer for S-Band Wireless Applications

“…In the current reuse mixer [11][12][13][14], the dissipated current in any stage is reuse in other stages, but the stacked transistors are not reduced, and the supply voltage is not decreased. Modified Gilbert mixers with folded structure had been reported in [15][16]. The folded Gilbert mixers could reduce the number of stacked transistors and loads, and work at a lower supply voltage, which is a better choice for portable communication system.…”
