Furthermore, a novel technique using nulling resistors to remove the RHP zeroes is discussed which greatly improves frequency and slew-rate performance, without increasing the power consumption. Thanks to the small compensation capacitors employed, the approach is suited for integration and in particular where large load capacitors have to be driven. SPICE simulations based on a 0.8-/spl mu/m CMOS design are given and found in remarkable agreement with the theoretical analysis.","PeriodicalId":166604,"journal":{"name":"2000 Southwest Symposium on Mixed-Signal Design (Cat.

Third generation is built on the backward compatibility with the second generation networks. Thus wideband multi-standard receivers, which are able to operate according to multiple mobile communication standards, will be required by the third generation system users. This paper presents a number of system issues and design considerations which are involved in the design of wideband multi-standard DCS1800/UMTS digital receiver, and in particular the analog-to-digital converter (ADC) technology requirements for the implementation is presented.","PeriodicalId":166604,"journal":{"name":"2000 Southwest Symposium on Mixed-Signal Design (Cat.

Due to the relatively slower bus clocks compared to the processor, it is necessary to use phase-locked loops (PLL) for multiplication and phase aligning of the clocks. A PLL is composed of both digital and analog components and is not modeled well in a design environment for digital systems. There are design tools available that are more adept for doing PLL simulations; however, they can be very costly and are still not suitable for the way PLL's are used in computer systems. The goal of this paper is to introduce a new simulator that is specifically designed for simulating PLL's used in computer systems.","PeriodicalId":166604,"journal":{"name":"2000 Southwest Symposium on Mixed-Signal Design (Cat.

One such optoelectronic-VLSI (OE-VLSI) technology is based on the hybrid flip-chip area bonding of GaAs/AlGaAs multiple-quantum well (MQW) electro-absorption modulator devices directly onto active silicon CMOS circuits. The technology has reached the point where batchfabricated foundry shuttle incorporating multiple OE-VLSI chip designs are now being run. These foundry shuttles represent the first delivery of custom-designed CMOS VLSI chips with surface-normal optical I/O technology. From a systems point of view, this represents an important step towards the entry of optical interconnects in that: the silicon integrated circuit is state-of-the-art; the circuit is unaffected by the integration process; and the architecture, design, and optimization of the chip can proceed independently of the placement and bonding to the optical I/O.","PeriodicalId":166604,"journal":{"name":"2000 Southwest Symposium on Mixed-Signal Design (Cat.

To tradeoff between hardware complexity and glitch performance the current practice is to use a hybrid converter where the most significant bits are thermometer coded and the least significant bits are binary-scaled. As an alternative to this scheme, we propose a new method for D/A conversion based on linear coding of the weights (1, 2, 3,...). The new method improves the glitch performance and reduces the hardware complexity for high resolution converters. An algorithm for converting the digital binary-coded input word into a digital word controlling the linear weights is given. In an example, the linear-coded weights are applied to a current-steering D/A converter. We discuss properties such as layout properties, device matching, and mixed-signal issues.","PeriodicalId":166604,"journal":{"name":"2000 Southwest Symposium on Mixed-Signal Design (Cat.

Tests are generated by manipulating, in a systematic yet simple way, sets of pairs of functions.

A test that detects many faults is generated from each pair of functions.
