This paper describes a 802.15.6 compliant 2360-2484MHz multiband transmitter that digitally multiplexes the appropriate phases from an 800MHz poly-phase filter output to generate &#x03C0;/4 DQPSK signals at 2.4GHz. Modulation at 1/3<sup>rd</sup> the RF frequency reduces the transmitter power consumption and enables channel selection using a PLL running at(More)
A low power low noise 0.7V mixer first RF frontend for an IEEE 802.15.6 narrowband receiver is presented which uses passive coupling based frequency translated mutual noise cancellation. Unlike traditional noise cancelling techniques we perform symmetrical noise cancellation of a fully differential structure where each path cancels the noise of the other at(More)
A low-power low-noise 0.7-V mixer-first RF frontend for an IEEE 802.15.6 narrowband receiver is presented, which uses frequency translated mutual noise cancellation based on passive coupling. Unlike traditional noise-cancelling techniques, we perform symmetrical noise cancellation of a fully differential structure where each path cancels the noise of the(More)
A 0.7V low power LNA combines a 1&#x2236;3 frontend balun with dual-path noise and non-linearity cancellation for improved noise performance at low power. In traditional techniques only the noise of the main path is cancelled while the noise of the auxiliary path is minimized by using high power. In the proposed design, the noise and non-linearity of both(More)
