In this talk we will discuss challenges in designing a D-Band radar for consumer and automotive applications. First, we will address: what is the optimal frequency for LO signal generation (VCO fundam...
This paper presents a 38-41 GHz direct-conversion I/Q transmitter in 0.12-μm GaN technology that achieves high linearity and low error-vector-magnitude (EVM) for high-order 4096-QAM modulation. The pr...
Over the last decade, the complexity of RF component packaging has increased, driven by, for example, the integration of multiple semiconductor dies into compact, high-performance systems. This evolut...
This paper presents an ultra-compact and broadband fully-differential rat-race coupler in 180-nm CMOS process, utilizing a novel folded inverted coupled-line (FICL) structure. By tuning the coupling c...
Millimetre-wave FMCW radar enables non-contact, high-precision thickness measurement; however, practical micrometre-level precision is limited by mechanical vibration, local-oscillator (LO) phase nois...
We present 145 GHz power amplifiers (PAs) in 22-nm FD-SOI technology with state-of-the-art low DC power consumption and small die area. Two distinct linearization architectures are demonstrated: a PA ...
