10-Gb/s DFE를 위한 Tunable Continuous-Time Linear Equalizer의 설계

In this paper, 10-Gb/s tunable continuous-time linear equalizer is proposed. Since DFE adaptation loop requires adjustments of DC gain and gain boosting of CTLE, degeneration capacitor and resistor of CTLE is tunable. To achieve required bandwidth, negative capacitance circuit is used. The proposed CTLE enhances eye opening by 40%. The proposed CTLE was realized in 65nm CMOS technology and simulation was done by HSpice.
