Com o aumento da escala tecnológica e o uso de tensões mais baixas, mais interesse de pesquisa está sendo mostrado no projeto de front-end analógico tolerante à variabilidade. Neste artigo, descrevemos um transmissor de controle de amplitude adaptativo que é operado usando sinalização diferencial para reduzir o efeito da variabilidade de temperatura. Ele permite operação de baixa potência e baixa tensão por sinergia entre controle de amplitude adaptativo e Vth controle de variação de temperatura. É adequado para aplicações de interface de alta velocidade, principalmente interfaces de cabo. Ao instalar um circuito agressor para estimar o jitter do transmissor e alterar sua frequência e taxa de ativação, conseguimos analisar os efeitos do bloco de interface no buffer de entrada e daí em todo o sistema. Também relatamos uma estimativa detalhada da operação de recuperação de dados de clock do receptor (CDR) para estimativa de jitter do transmissor. Estas investigações fornecem sugestões para ampliar a abertura ocular do transmissor.

Abstract: With increasing technology scaling and the use of lower voltages, more research interest is being shown in variability-tolerant analog front end design. In this paper, we describe an adaptive amplitude control transmitter that is operated using differential signaling to reduce the temperature variability effect. It enables low power, low voltage operation by synergy between adaptive amplitude control and Vth temperature variation control. It is suitable for high-speed interface applications, particularly cable interfaces. By installing an aggressor circuit to estimate transmitter jitter and changing its frequency and activation rate, we were able to analyze the effects of the interface block on the input buffer and thence on the entire system. We also report a detailed estimation of the receiver clock-data recovery (CDR) operation for transmitter jitter estimation. These investigations provide suggestions for widening the eye opening of the transmitter.
