IR-UWB radar demonstrator for ultra-fine movement detection and vital-sign monitoring
In this paper an impulse-radio ultra-wideband (IR-UWB) hardware demonstrator is presented, which can be used as a radar sensor for highly precise object tracking and breath-rate sensing. The hardware consists of an impulse ...
A 60 to 77 GHz switchable LNA in an RF-MEMS embedded BiCMOS technology
In this letter, a 60 to 77 GHz switchable low-noise amplifier is presented. The IC is realized in a radio frequency microelectro-mechanical systems embedded 0.25 µm SiGe-C BiCMOS technology. Measured results show that the ...
Multi-Gb/s analog synchronous QPSK demodulator with phase-noise suppression
In this paper, an IF quadrature phase-shift keying demodulator is presented, which performs phase and frequency synchronization in the analog domain. The presented demodulator can be utilized for short-range ultra-wideband ...
This article presented the possibilities of making microwave and mm-wave ICs more intelligent through a combination of established Si/SiGe BiCMOS technologies, which allow for complex ICs combining a multitude of high-speed ...
A 64-84-GHz PLL with low phase noise in an 80 GHz SiGe HBT technology
This paper presents a 64-84 GHz phase-locked loop (PLL) realized in a low-cost 80-GHz HBT technology. The circuit consists of a wide tuning-range voltage-controlled oscillator, a push-push frequency doubler, a divide-by-32 ...
Design and comparison of regenerative dynamic frequency dividers in different configurations using SiGe HBT technology
In this letter, the authors present the design, analysis and comparison of a series of dynamic frequency dividers. These dividers, each consisting of a Gilbert cell mixer core, a transimpedance amplifier and an emitter-follower ...
