1. Design of self-checking fully differential circuits and boards
A design methodology for on-line testing analog linear fully differential (FD) circuits is presented in this work. The test strategy is based on concurrently monitoring via an analog checker the common mode (CM) at the inputs of all amplifiers. The totally self-checking (TSC) goal is achieved for linear FD implementations provided that the checker CM thresho

2. Mixed-signal analog-digital circuits design on the pre-diffused digital array using trapezoidal association of transistors
The mixed-signal and analog design on a pre-diffused array is a challenging task, given that the digital array is a linear matrix arrangement of minimum-length transistors. To surmount this drawback a specific discipline for designing analog circuits over such array is required. An important novel technique proposed is the use of TAT (Trapezoidal Association

3. Planejamento de teste de sistemas baseados em núcleos de hardware de sinal misto usando bist
Atualmente, os sistemas eletrônicos integrados seguem o paradigma do projeto baseado em núcleos de hardware. Além de núcleos digitais, tais sistemas podem incluir núcleos analógicos, que, neste caso, dominam os requisitos de teste, como tempo de teste e número adicional de pinos. Consequentemente, há um aumento do custo total de manufatura do disposi

4. Digital approach for the design of statistical analog data acquisition on SoCs / Uma abordagem digital para o projeto de aquisição estatística de dados analógicos em sistemas Integrados (SoCs).
With the current demand for mixed-signal SoCs, an increasing number of designers are looking for ADC architectures that can be easily implemented over digital substrates. Since ADC performance is strongly dependent upon physical and electrical features, it gets more difficult for them to benefit from more recent technologies, where these features are more va
