a high accurate and low-voltage analog cmos current divider which operates with a single power supply voltage is designed in 0.18µm cmos standard technology. the proposed divider uses a differential amplifier and transistor in triode region in order to perform the division. the proposed divider is modeled with neural network while tlbo algorithm is used to optimize it. the proposed optimization...

Traditionally, multiple IC chips are needed to build transmitters (Tx) used in wireless communications. The difficulty with a full Tx integration is that each Tx building block uses different technology. A power-detection circuit will exploit the Schottky diode, while the modulator IC is integrated with BiCMOS or SiGe. Likewise, the digital control loop is implemented in CMOS. Now that directco...

This paper presents a very low-power and fully programmable CMOS digital active pixel sensor for uncooled IR fast imaging. The proposed circuit topology includes selfbiasing, built-in input capacitance compensation, predictive A/D conversion and a truly digital I/O interface, all at pixel level. Furthermore, full FPN cancellation is also supplied by the external digital tuning of both offset an...

This paper presents two highly integrated receiver circuits fabricated in InP heterojunction bipolar transistor (HBT) technology operating at up to 2.5 and 7.5 Gb/s, respectively. The first IC is a generic digital receiver circuit with CMOS-compatible outputs. It integrates monolithically an automatic-gain-control amplifier, a digital clock and data recovery circuit, and a 1 : 8 demultiplexer, ...

The synthesis of digital circuits is generally performed in two level logic switching algebra. But if we increase the representation domain from two level logic (N=2) to N>2 then the design of Multiple Valued Logic (MVL) digital circuits is possible. Interconnections play an important role in deep submicron designs as they affects power and area. Due to the requirement of interconnections the d...

An analogue adaptive filter for dynamic response compensation of a load cell sensor is presented. The filter employs only transistors and therefore it can be integrated using standard digital CMOS technology, which is suitable for System-on-Chip applications. To perform adaptive compensation over a wide range of measurand, a novel CMOS multiplier circuit was developed. The analogue adaptive fil...

(ABSTRACT) The explosive growth in wireless communications has led to an increased demand for wireless products that are cheaper, smaller, and lower power. Recently there has been an increased interest in using CMOS, a traditional digital and low frequency analog IC technology, to implement RF components such as mixers, voltage controlled oscillators (VCOs), and low noise amplifiers (LNAs).
