This paper describes the design of a bandgap reference, implemented in 0.50 μm CMOS technology. The circuit generates a reference voltage of 1.2218V. It can operate between 20oC & 70o C. Total variation of reference voltage within the temperature range is 2.6mV which is 0.213% of the reference voltage. This circuit works in a current feedback mode, and it generates its own reference current, re...

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...

In this paper, design and analysis of a programmable CMOS-based function generator circuit is presented. The proposed circuit implements trapezoidal and triangular functions with all parameters (slope, position, width and height) independently and continuously adjustable. The proposed circuit achieves higher speed compared to the available previous work by not using winner takes all or looser t...

The design automation of analog CMOS integrated circuits (ICs) is a demanding task in microelectronics industry, because of the crescent necessity for low-power design and reduced time-to-market. Nowadays, most analog sizing designs are done manually with some aid of simulation tools and equation-based models and the quality of the resulting circuit is dependent on the expertise of the designer...

A novel CMOS tunable transconductor is presented. The circuit operates in classAB hence featuring power efficiency. The internal feedback employed and the use of a linearized triode transistor for voltage-to-current conversion allows achieving high linearity. Rail-to-rail input range is obtained by using floatinggate transistors. Measurement results for a test chip prototype in a 0.5μm standard...

The continuous increase of integration densities in Complementary Metal–Oxide–Semiconductor (CMOS) technology has driven the rapid growth of very large scale integrated (VLSI) circuit for today's high-tech electronics industries from consumer products to telecommunications and computers. As CMOS technologies are scaled down into the nanometer range, analog and mixed integrated circuit (IC) desi...

Abstract: Analog sampling systems based on switched capacitor techniques offer performance superior to that of flash A/D converters with respect to cost, density, dynamic range, sampling speed, and power consumption. This paper proposes a 500 MHz switched capacitor analog waveform sampling circuit for the camera electronics of the Cherenkov telescope. An experimental 4 channel analog memory wit...

The analog IC technology, might sound old-fashioned, is still important for the future wireless systems such as 4G cellular phone systems, broadband wireless networkings, and wireless sensor networkings. The analog features and issues of the scaled CMOS transistor, the basic issue and the technology trend for the ADC as an important building block of wires systems, and the feature of the digita...

This paper presents a general-purpose sampled-data analogue processing element that essentially functions as an analogue microprocessor (AμP). The AμP executes software programs, in a way akin to a digital microprocessor, while nevertheless operating on analogue sampled data values. This enables the design of mixed-mode systems which retain the speed/area/power advantages of the analogue signal...

An analog VLSI circuit model of the vocal tract is described. The vocal tract is acoustically modeled as a series of uniform cross-section tubes concatenated end-to-end. Each section of tube is modeled as an RLC circuit whose element values are determined by its area and length with the current and voltage corresponding to volume velocity and pressure in the tube. An analog VLSI circuit is desc...
