Query: Design Considerations of a Sub-50 {\mu}W Receiver Front-end for
  Implantable Devices in MedRadio Band   Emerging health-monitor applications, such as information transmission
through multi-channel neural implants, image and video communication from
inside the body etc., calls for ultra-low active power (<50${\mu}$W) high
data-rate, energy-scalable, highly energy-efficient (pJ/bit) radios. Previous
literature has strongly focused on low average power duty-cycled radios or low
power but low-date radios. In this paper, we investigate power performance
trade-off of each front-end component in a conventional radio including active
matching, down-conversion and RF/IF amplification and prioritize them based on
highest performance/energy metric. The analysis reveals 50${\Omega}$ active
matching and RF gain is prohibitive for 50${\mu}$W power-budget. A mixer-first
architecture with an N-path mixer and a self-biased inverter based baseband
LNA, designed in TSMC 65nm technology show that sub 50${\mu}$W performance can
be achieved up to 10Mbps (< 5pJ/b) with OOK modulation.
