A 60 GHz reconfigurable active phase shifter based on a vector modulator in 65 nm CMOS technology

This paper presents a 60 GHz reconfigurable active phase shifter based on a vector modulator implemented in 65 nm complementary metal–oxide–semiconductor technology. This circuit is based on the recombination of two differential paths in quadrature. The proposed vector modulator allows us to generate a phase shift between 0° and 360°. The voltage gain varies between −13 and −9 dB in function of the phase shift generated with a static consumption between 26 and 63 mW depending on its configuration.

60GHz highly reliable power amplifier with 13dBm P sat 15% peak PAE in 65nm CMOS technology

A 60 GHz highly reliable single-ended two-stage Power Amplifier (PA) is fabricated for the Wireless Personal Area Network (WPAN) applications. The PA consists of a cascode power stage to reduce voltage drop and improving long-term reliability, and a common source driver stage. Output, inter-stage and input impedance matching networks are implemented with distributed elements (microstrip and slow-wave transmission lines). The PA achieves a saturated output power (Psat) of 13dBm and a maximum Power Added Efficiency (PAEmax) of 15% with 13dB gain. It consumes only 84mW and occupies 0.4mm2 of die area.
