In this paper, a novel model for accurately evaluating the performance behaviour of subharmonic self-oscillating mixers (SOM) is presented. This model permits to investigate on the effects of various design parameters of SOMs namely in terms of conversion gain, IF frequency, noise figure, and intermodulation distortion. Such an accurate model is specifically important in the design of millimeter-wave...
This paper describes a fully-integrated 77-GHz distant-selective pseudo-random noise coded Doppler radar transceiver in a Silicon-Germanium technology. The transceiver is capable of measuring a vibration or a velocity of a target at a specified distance, which is programmable and can be configured very precisely in the transceiver, and suppressing all other targets elsewhere. It is equipped with two...
This paper describes a fully-integrated 77-GHz ultra-wideband pseudo-random noise (PRN) radar transceiver in a Silicon-Germanium technology. The transceiver is equipped with a programmable pseudo-random binary sequence (PRBS) generator, which is realized in a current-mode logic topology and can be operated with a clock rate of up to 4.25 GHz to enable a range resolution of 3.5 cm. The signal generation...
