We present fully integrated high-performance voltage-controlled oscillators (VCOs) with on-chip microelectromechanical system (MEMS) inductors for the first time. MEMS inductors have been realized from the unique CMOS-compatible MEMS process that we have developed to provide suspended thick metal structures for high-quality ( ) factors. Fully integrated CMOS VCOs have been fabricated by monolit...

Low power wireless sensor networks provide a new monitoring and control capability for civil and military applications in transportation, manufacturing, biomedical technology, environmental management, and safety and security systems. Low power integrated CMOS systems are being developed for microsensors, signal processors, microcontrollers, communication transceivers and network access control...

Operational amplifiers are an integral part of many analog and mixed signal systems. As the demand for mixed mode integrated circuits increases, the design of analog circuits such as operational amplifiers in CMOS technology becomes more critical. This paper presents a two stage CMOS operational amplifier, which operates at ±1.8V power supply using TSMC 0.18um CMOS technology. The OP-AMP design...

This paper presents a new method for hierarchical characterization of analog integrated circuits. For each circuit class, a fundamental set of performances is defined and extracted topology-independently. A circuit being characterized is decomposed in general subcircuits. Sizing rules of these topology-independent subcircuits are included into the characterization by functional constraints. In ...

Graphene/silicon CMOS hybrid integrated circuits (ICs) should provide powerful functions which combines the ultra-high carrier mobility of graphene and the sophisticated functions of silicon CMOS ICs. But it is difficult to integrate these two kinds of heterogeneous devices on a single chip. In this work a low temperature process is developed for integrating graphene devices onto silicon CMOS I...

SiSMA (Simulator for Statistical Mismatch Analysis) is a CAD tool for the statistical analysis of analog CMOS integrated circuits affected by technological tolerance effects including device mismatch.

This is a very brief review of the recent work on the development of hybrid semiconductor/nanodevice integrated circuits. Such a circuit will combine a CMOS subsystem, and a nanowire crossbar with simple bistable two-terminal devices formed at each crosspoint, connected with an area-distributed “CMOL” interface. Simulations have shown that the hybrid circuits may serve as the basis for (i) tera...

This paper presents a new general purpose neuro-fuzzy controller to realize adaptive-network-based fuzzy inference system (ANFIS) architecture. ANFIS which tunes the fuzzy inference system with a back propagation algorithm based on collection of input-output data makes fuzzy system to learn. To implementing this idea we propose several improved CMOS analog circuits, including Gaussian-like memb...

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...
