A 24GHz CMOS RF Transceiver for Car Radar Applications

This paper describes a 24GHz CMOS RF transceiver for car radar applications. The transceiver consists of 4-channel receiver array and 1-channel transmitter. The prototype is designed by standard RF CMOS 0.13-μm technology. The simulated receiver gain is 30dB and simulated tramsmitted output power is 15dBm at 24GHz.

A 24GHz, +14.5dBm fully-integrated power amplifier in 0.18 μm CMOS

A 24GHz, +14.5dBm fully-integrated power amplifier with 50Ω input and output matching is fabricated using 0.18μm CMOS transistors. To enable this, a shielded-substrate coplanar waveguide transmission line structure is used to achieve low loss and small area. The power amplifier achieves a power gain of 7dB and a maximum single-ended output power of +14.5dBm with a 3dB bandwidth of 3.1GHz, while...

Low-Power Power Amplifier for 77-GHz Automotive Radars

In this paper we present low-power 77-GHz power amplifier (PA) for the long range automotive radar. The proposed amplifier is designed using TSMC 0.13-μm RF CMOS (fT/fmax=120/140 GHz) technology, and it is powered by a 1.5V supply. To reduce power dissipation, we consider bias voltage, transistor size optimization, matchings and layout optimization. To improve power gain of the amplifier, it ha...

Millimeter-wave CMOS Transceiver Techniques for Automotive Radar Systems

Recently, advanced driver assistance systems (ADAS) with the keyword of “safety” have attracted attention in the world.
