*Equally Credited Authors (ECAs) Abstract A hydrogel-based single-culture dual-fluorescence sensor is presented for bioavailable phosphorus (P) detection. The sensor achieves 6.6fA sensitivity with a 15.5dB SNR and an ou

The integration of electronics and photonics into a single silicon CMOS process can serve wide-ranging applications, e.g. complex imaging and projection photonic systems, onchip optical interconnects, or self-correcting

Low-cost mm-wave silicon integrated signal generation and processing enable many applications, such as silicon-based automotive radars for self-driving cars and wireless communications. Some challenges encountered in com

Cost-efficient, point-of-use diagnostics are critical for early disease detection. Traditionally, the majority of lab-based analysis equipment utilizes fluorescent markers for biodetection assays. However, magnetic-based

Modern SoC systems impose stringent requirements on on-chip clock generation and distribution. Ring-oscillator (RO) based injection-locked (IL) clocking has been used in the past [1] to provide a low-power, low-area and

There is high demand for at-home and point-of-care medical diagnostic tools as a step toward fast, low-cost, personal medicine. Integrated biosensors based on magnetic labeling schemes offer higher sensitivity and lower

Up until recently, the terahertz frequency range (0.3 to 3THz) has been mostly addressed by high-mobility custom III-V processes, bulky and expensive nonlinear optics, or cryogenically cooled quantum cascade lasers. A lo

The increasing demand for high-bandwidth interconnection between integrated circuits requires large numbers of I/Os per chip as well as high data rates per I/O. Key limitations in meeting these requirements include chann

Despite the aggressive scaling of silicon-based IC’s over the past few decades, the transistor characteristics have yet to improve so that the ‘THz’-range (~300GHz-to-3THz) circuits can be effectively designed using the

The ever-increasing demand for higher data rates in communication links has created a need for power amplifiers with large instantaneous bandwidth. Moreover, software-defined radio and smart antenna systems require power

Future Point-of-Care (PoC) molecular-level diagnosis requires advanced biosensing systems that can achieve high sensitivity and portability at low power consumption levels, all within a low price-tag for a variety of app

Non-constant envelope modulation schemes have become commonplace in cellular applications due to their higher spectral efficiency. Linear PAs driven by an RF transmitter are usually used to generate these signals faithfu

The noise figure (NF) of a front-end low-noise amplifier (LNA) places a lower bound on the sensitivity of a receiver. In a conventional LNA, there is a tradeoff between the intrinsic input capacitance of the input transi

In typical radio transmitters, the signal is modulated at lower frequencies and then up-converted, amplified, and radiated by an antenna. In the absence of multi-path, receivers at different angles observe the same modul

As scaling reduces the breakdown voltage of CMOS devices and as system integration trends demand the further elimination of offchip components, there arises a great need to improve the linearity of RF receivers. Of parti
