1. A compact model of MOSFET mismatch for circuit design
This paper presents a compact model for MOS transistor mismatch. The mismatch model uses the carrier number fluctuation theory to account for the effects of local doping fluctuations along with an accurate and compact dc MOSFET model. The resulting matching model is valid for any operation condition, from weak to strong inversion, from the linear to the satu

3. An estimation method for gate delay variability in nanometer CMOS technology
In the nanoscale regime of VLSI technology, circuit performance is increasingly affected by variational effects such as process variations, power supply noise, coupling noise and temperature changes. Manufacturing variations may lead to significant discrepancies between designed and fabricated integrated circuits. Due to the shrinking of design dimensions, t

4. Circuitos integrados de radio-recepção para a operação de multiplexação espacial de antenas em tempo real / Integrated circuits of radio-reception for spatial multiplexing of antennas in real time
This research aims the conception of new topologies of integrated circuits and its characterizations for operation in radio-receiver systems. The design and fabrication of RF switches, LNAs, mixer, and VCOs are presented. The SMILE - Spatial MultIplexing of Local Elements - technique was adopted due to its advantages and functionality for the intelligent ant

5. Project of circuits for generation of voltage reference in receiving/transmitting RF systems. / Projeto de circuitos para geração de tensão de referência em sistemas receptores/transmissores RF.
This work consists in the design of a CMOS Voltage Reference Source with a temperature coefficient inferior to 50 ppm/ºC. This voltage source should be applied in radio frequency receptor/transmitter but can be also applied in any analog system. The technology employed in the design is the CMOS 0.35 µm from the AMS (Austria Micro Systems) with four metal l
