A new CMOS-based image sensor that is intrinsically compatible with onchip CMOS circuitry is reported. The new CMOS active pixel image sensor achieves low noise, high sensitivity, X-Y addressability, and has simple timing requirements. The image sensor was fabricated using a 2 pm p-well CMOS process, and consists of a 128 x 128 array of 40 pm x 40 pm pixels. The CMOS image sensor technology ena...

Digital video technology has been characterised by continued growth in the last decade. The uses of video coding are broad and diverse. However, generally they fall into two main categories either utilising limited storage or transmission bandwidth. Video coding is essential for video on Digital Versatile Disc (DVD) and utilising the limited bandwidth available for realising real time applicati...

The integrated circuit revolution has impacted virtually all fields of engineering. The main driving force behind this revolution is Complementary Metal-Oxide Semiconductor (CMOS) transistor technology. As CMOS integrated circuit “chips” have come to dominate analog and digital electronics, introductory electronics courses in Electrical and Computer Engineering programs have evolved to place gr...

This work presents two current-mode integrated circuits designed for sensor signal preprocessing in embedded systems. The proposed circuits have been designed to provide good signal transfer and fulfill their function, while minimizing the load effects due to building complex conditioning architectures. The processing architecture based on the proposed building blocks can be reconfigured throug...

Voltage boosting from CMOS photovoltaic device (PV) is achieved by implementing multiple PV units on single CMOS chip and are series connected by an external integrated passive device. Localized substrate removal process is developed to electrically isolate the PV units. Four-cell cascaded CMOS PV module provides an open-circuit voltage of 2.05 V while maintaining its superior PV performance.

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...

A new first order voltage mode all-pass filter circuit using two differential difference current conveyors (DDCCs) (with suppressed output stages) as active elements and two passive components is proposed. The given circuit enjoys the features of high input impedance and low output impedance, which is desirable feature for voltage-mode circuits. In spite of employing two active elements the cir...

In almost all of the currently working circuits, especially in analog circuits implementing signal processing applications, basic arithmetic operations such as multiplication, addition, subtraction and division are performed on values which are represented by voltages or currents. However, in this paper, we propose a new and simple method for performing analog arithmetic operations which in thi...
