Fundamental Limitations of Circuit Architectures / High Power Terahertz Signal Generation

We have developed a theoretical framework for analyzing the fundamental frequency and power limitations of various circuit architectures and exploit the results to design novel circuits with significantly better performance. Broadly speaking, the main innovation in this work is the introduction of a systematic methodology for designing circuits operating at the limits of the transistors in any given process. This is achieved by blending device physics, circuit theory, and high frequency circuit design into a coherent technique. As an example, this method led to the implementation of a 482 GHz oscillator in a 65 nm CMOS process with an output power of 160 μW.

Novel Traveling-Wave Circuits for Extremely Wide Band Signal Generation

Inspired by the Doppler effect and using the traveling-wave properties, we proposed a novel wideband frequency multiplier that efficiently generates and combines the harmonics of the input signal. The implemented frequency doubler operates from 220 GHz to 275 GHz in a 65 nm CMOS process with an output power of -6.6 dBm at 244 GHz.

Electrical Prism: A High Quality Factor Filter Using 2-D Electrical Lattices

A method to perform high performance signal processing using 2-D electrical lattices is introduced. Using the anisotropic behavior of these lattices, we proposed an Electrical Prism that can achieve a filtering quality factor which is orders of magnitude larger than the quality factor of the individual components in terahertz frequencies. an electrical prism with quality factor of 420 at 460 GHz consisting of elements with the quality factor 20 was presented.

High Speed Inductor-less TIA

A new technique to enhance the gain-bandwidth product of a transimpedance amplifier (TIA) without using any inductor was proposed. A 10-Gb/s TIA with an active area of only 0.06 mm2 was implemented for high speed parallel optical links for chip-to-chip and intra-chip interconnections.
