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 operated using differential signaling to reduce temperature variability effect. It enables low power, voltage operation by synergy between Vth variation control. suitable for high-speed interface applications, particularly cable interfaces. By installing aggressor circuit estimate jitter changing its frequency activation rate, were able analyze effects block on input buffer thence entire system. We also report a detailed estimation receiver clock-data recovery (CDR) estimation. These investigations provide suggestions widening eye opening transmitter.
