This paper proposes to merge an I/Q current-commutating mixer with a noise-canceling balun-LNA. To realize a high bandwidth, the real part of the impedance of all RF nodes is kept low, and the voltage gain is not created at RF but in baseband where capacitive loading is no problem. Thus a high RF bandwidth is achieved without using inductors for bandwidth extension. By using an I/Q mixer with 2...

5.1 INTRODUCTION MIMO wireless systems have demonstrated the potential to increase communication spectral efficiency in a rich multipath environment. From an antennas perspective, different array configurations and types of element have been proposed and analyzed for MIMO links. Nowadays in military and commercial applications there have been ever growing demands for antennas. The standard dipo...

This work presents a high efficiency RF-to-DC conversion circuit composed of an LC-CL balun-based Gm-boosting envelope detector, low noise baseband amplifier, and offset canceled latch comparator. It was designed to have sensitivity with power consumption for wake-up receiver (WuRx) applications. The proposed detector is based on fully integrated inductively degenerated common-source amplifier ...
