This paper presents the design and simulation of a 5GHz monolithic low-noise amplifier integrated with an active Balun. Intended to WLAN applications, the fully integrated circuit was implemented in a 0.18μm CMOS technology. The simulations, optimized to noise performance, gain and minimum differential phase and magnitude error, were performed with BSIM3 model. Circuit simulations present 23dB ...

A CMOS four-quadrant analog multiplier circuit for neural networks integrated circuit implementation is presented. By applying differential balanced current mode signals (both for the input, output and weight signals) the multiplication function is easily implemented through two translinear loops. The multiplier exhibits low power consumption (the dc current is 250 nA under a differential power...

ICID (Integrated Circuit IDentification) is a small mixed-signal cell that can be added to the test logic on a CMOS integrated circuit. It provides a unique 224 bit identification number that can be accessed during die test. This identification can be used to correlate test information for individual die on the wafer, through package test, and into the field and back. The identification bits ar...

Phased array systems, a special case of MIMO systems, take advantage of spatial directivity and array gain to increase spectral efficiency. Implementing a phased array system at high frequency in a commercial silicon process technology presents several challenges. This article focuses on the architectural and circuit-level trade-offs involved in the design of the first silicon-based fully integ...
