Abstract
In this paper, we propose 24-GHz CMOS radio frequency (RF) power amplifier for short-range automotive collision avoidance radars. This circuit contains common source stage with inter-stages conjugate matching circuit as a class-A mode amplifier. The proposed circuit is designed using TSMC $\small{0.13-{\mu}m}$ mixed signal/RF CMOS process ($f_T/f_{MAX} Keywords 24GHz;automotive collision avoidance;CMOS power amplifier;transmission lines; Language Korean Cited by References 1.
