This paper discusses some of the advantages and of the disadvantages of using a CMOS process in the 180 – 100 nm range for the design of analog blocks in mixed-mode integrated circuits.

Presented method of on-line detection of overloads and short circuits in digital devices and systems is based on inexpensive overload detectors built into integrated circuits. A prototype 0.8 μm CMOS ASIC successfully verifies this method.

Circuit sizing problem in application specific analog integrated circuit design is in most cases limited to setting MOSFET channel widths and lengths. It is usually performed by hand by an experienced human designer. As the circuit sizing is an optimization process by its nature, optimization methods could be used. They always lead to one of the minima of the cost function while eventual other ...

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...

In this paper, ultra-low-voltage and ultra-lowpower circuit techniques are presented for CMOS RF front-ends. By employing a modified current-reused architecture, the low-noise amplifier (LNA) can operate at a very low supply voltage with microwatt power consumption while maintaining reasonable circuit performance at 2.4 GHz. Using a TSMC 0.18 um CMOS process, from the simulation results, the fu...

Radiation detectors were developed by depositing 20 μm thick hydrogenated amorphous silicon (a-Si:H) sensors directly on top of the so-called aSiHtest integrated circuit. This circuit was designed in a quarter micron CMOS technology as a global test circuit for this novel detector technology. The sensor leakage current turned out to be limiting the performance of the whole detector. Its detaile...

The current mirror is one of the necessary parts in CMOS (Complementary Metal Oxide Semiconductor) analog circuit design. The current mirror can be used as an active element and as a biasing circuit. The circuit structures are supposed to be compatible with low-voltage operating environments to avoid the decrement in system performance caused by the low-voltage low-power designs including reduc...

The integrated circuit design of a switched-capacitor filter for Bluetooth specifications is described. It was based on the optimum allocation of poles and zeros to generate a transfer function with unequal numerator and denominator orders, so that a direct-form structure with reduced number of opamps and low sensitivity to capacitor ratio errors were obtained. It was designed for implementatio...
