Operational amplifiers are important building blocks for analog circuit design. Unfortunately, their limited performance such as bandwidth, slew-rate etc. leads the analog designer to search other possibilites and other building blocks. As a result, new current-mode active building blocks such as operational transconductance amplifiers (OTA), second generation current conveyors (CCII), current-...

Introduction: On-chip integrated circuits often need to be tunable to correct for process or temperature variations. However, unpredictable or unknown device characteristics make it hard to implement tunable linear circuits. In modern submicron CMOS technologies, the transistor characteristics can deviate significantly from the ideal behaviour. In this Letter a continuously tunable current divi...

A simple analytical model to predict the DC MOSFET behavior under electromagnetic interference (EMI) is presented. The model is able to describe the MOSFET performance in the linear and saturation regions under EMI disturbance applied to the gate. The model consists of a unique simple equivalent circuit based on a voltage dependent current source and a reduced number of parameters which can acc...

Failure analysis challenges have increased as electronic circuit capability and complexity of integrated circuits evolve to higher densities and smaller feature sizes. Despite this evolution, “old school” tools can be effective in solving problems on both simple and complex devices. In particular, when Voltage Contrast (VC) and Electron Beam Induced Current (EBIC) are combined together results ...

This paper proposes a circuit to linearize the signal current and improve the distortion characteristics at the input of a current-mode circuit. Input voltage-to-current (V/I) conversion is carried out by a resistor that connects the signal source and the current input terminal of the current-mode circuit. The signal current flowing into the current-mode circuit through this resistor is distort...
