This paper presents a sub-harmonic mixer IC design for W-band automotive radar applications in 130-nm SiGe BiCMOS technology. The mixer makes use of a Common Emitter Common Collector Transistor Pair (CECCTP) structure mixer core with a Marchand balun for the W-band on-wafer measurement. The balun achieves a measured amplitude imbalanced of less than 0.9 dB and a phase imbalance of less than 2.5 degrees...
A miniaturized broadband balun IC in 180-nm CMOS is presented for millimeter-wave applications. The balun IC is designed so that high impedance ratio between the even and odd modes is achieved by utilizing Electro-magnetic solver suitable for planer structure. The fabricated balun IC in 180-nm CMOS process occupies only 0.03 mm2. The balun IC exhibits an amplitude imbalance of less than 0.9 dB and...
The acquisition of standard planes is crucial for medical ultrasound (US) diagnosis. In this paper, we present a hierarchical supervised learning framework for automatically detecting standard plane in consecutive 2D US images. The technique is demonstrated by developing a system that localizes fetal abdominal standard plane (FASP) from US videos. We first propose a novel radial component-based model...
This paper presents novel sub-harmonic mixer topologies for W-band automotive radar applications in 65nm CMOS technology. Working principle and performance of three kinds of topologies are analyzed and discussed with physical layout and EM simulation. The simulated performance shows a double side band noise figure of 20.8 dB and a voltage conversion gain of −8.7 dB at an RF frequency of 79.0001 GHz...
In this paper, novel linearization technique is proposed to realize a 5-GHz band linear CMOS power amplifier IC for WLAN application. The novel linearizer which consists of a diode-connected PMOS bias circuit and a PMOS varactor connected in parallel with an NMOS amplifier is effectively to suppress the gain compression and phase distortion of the power amplifier. A CMOS power amplifier IC is designed,...
This paper presents a low operation voltage ultrawideband power detector IC for microwave and millimeter-wave applications. The power detector circuit includes an nMOS transistor differential pair with a resistive feedback. The power detector IC was designed and fabricated using TSMC 130 nm CMOS technology. The detector IC exhibits an operation frequency from 100 MHz to 40 GHz at an operation voltage...
This paper presents a new object tracking model that systematically combines region and boundary features. Besides traditional region features (intensity/color and texture), we design a new boundary-based object detector for accurate and robust tracking in low-contrast and complex scenes, which usually appear in the commonly used monochrome surveillance systems. In our model, region feature-based...
