This paper presents optimization process, simulations and measurement results of a fully differential 60 GHz active down converter with resonating current bleeding in a 90 nm CMOS process. The circuit is thought to be used within a superheterodyne receiver with intermediate frequency at around 20 GHz, covering the four channels of the IEEE802.15.3c standard. Thanks to the careful optimization of the resonating current bleeding network, the quad introduced noise is minimized keeping the conversion gain and the required local oscillator power at reasonable values.

“…Matching networks may be necessary to enhance the operation bandwidth. Many reported mixer works, such as [8], [9], are focused on matching for the RF, LO or IF input ports of the mixer. In our design, the diode ring is directly matched with a pair of single-stub networks between the balun and diode ring, which realized a compact layout for the matching network, and greatly improved the return loss of the LO port, thus enhance the operation bandwidth of the mixer.…”

In this paper, the development of a Q-band doubly balanced mixer in 0.15um GaAs pHEMT process is presented. Five-conductor coupled line Marchand balun is designed and utilized for the LO and RF signal input. Instead of using conventional input port matching method, the complex impedance of the diode ring is directly matched with differential single-stub networks between the balun and diode ring, which realized a compact layout for the matching network, and greatly improved the return loss of the LO port, thus enhanced the mixer operation bandwidth. Measured results coincide well with the simulations: the conversion gain is -9.2dB ~ -11.9dB for RF and LO frequency from 40GHz ~ 50GHz, and IF frequency is DC ~ 10GHz, with the LO power level of +15dBm. The typical LO-RF isolation is 33 dB with minimum value of 19.3dB for LO between 35GHz to 50 GHz, and the IIP3 is above +12.6dBm for 40GHz ~ 50GHz, which is suitable for the China millimeter wave communication standard "Q-LINKPAN".Index Terms -Doubly balanced mixer, matching network, multi-conductor coupled line, Q-band.

Abstract�A transmission line-based integrated sensor is investigated for the dielectric constant characterization of liquids using pico-liter volumes. The sensor is manufactured using the back-end-of-line of a CMOS 0.35 11m from AMS. A simple maskless etching post-CMOS process is used to realize a cavity underneath a transmission line to insert the liquid-under-test. Measurements with a vector network analyzer demonstrate a promising method for the characterization of the dielectric constant of liquids up to 40 GHz.
