The THz region of the electromagnetic spectrum is gaining interest due to its unique spectroscopic properties that make it useful for gas detection, biological imaging, and accurate timekeeping. While several techniques

In THz imaging systems, signal sources are needed to provide illumination of objects. In several reported imaging systems working at 0.3THz, 0.62THz, and 0.81THz, an output power around 1mW is required to achieve an acce

The drive for higher data-rates has led to the allocation of the spectrum above 100GHz for D-band communication. A high level of integration in a nm-CMOS technology is necessary to keep the cost low and allow for efficie

Technology scaling has been very beneficial for digital circuits both in terms of speed and power. Traditional analog techniques however are challenged by the ever-decreasing supply voltages. Highly digital VCO-based ADCs

A fully integrated receiver for high-capacity 5G E-Band Backhaul links (71 to 76GHz and 81 to 86GHz) needs a local-oscillator (LO) distribution network with >19% tuning range (TR) and accurate quadrature phases. Further,

Technology scaling has enabled RF-CMOS circuits that operate in the millimeterwave frequency range (30 to 300GHz) where large bandwidths are available. These bandwidths can be exploited to increase data-rates of wireless

Modern high-data-rate communication systems such as LTE use spectrally efficient modulation schemes with a high peak-to-average power ratio (PAPR), placing stringent linearity demands on the RF power amplifiers (PA). The
