Web-Done design optimization and tuning of CTLE (PCIe Gen3,USB3 Gen1,Gen2) - Worked on Phase Interpolator, DCC , bias circuits, self bias designs for different SerDes PHYs. - … Active CTLE • Input amplifier with RC degeneration can provide frequency peaking with gain at Nyquist frequency • Potentially limited by gain-bandwidth of amplifier • Amplifier must be designed for input linear range • Often TX eq. provides some low frequency attenuation • Sensitive to PVT variations and can be hard to tune
An Adaptive Continuous-Time Linear Equalizer Using ... - IEEE Xplore
http://tera.yonsei.ac.kr/class/2016_1_2/lecture/Lect%209%20Equalizers.pdf WebThe CTLE block applies a linear peaking filter to equalize the frequency response of a sample-by-sample input signal. The equalization process reduces distortions resulting from lossy channels. The filter is a real one-zero two-pole (1z/2p) filter, unless you define the gain-pole-zero (GPZ) matrix. churches seymour tx
Inductorless CTLE for 20 Gb/s SerDes for 5G backhaul
WebMay 15, 2024 · A 5-13.5 Gbps multi-standard I/O link receiver is presented in this paper. An inductor-free CTLE, whose gain and bandwidth are highly adjustable, is achieved by using the second-order negative capacitance circuit. A high jitter tolerance clock and data recovery (HJTOL-CDR) is proposed for Spread Spectrum Clock applications. In this work, the … WebSep 16, 2024 · 44. 45 112-Gbps Electrical Interfaces: An OIF update on CEI-112G Meas. 45. 46 • Not making compliance measurements at this stage • Some silicon vendors are characterizing test chips and proprietary designs • Likely see some compliance testing in the next year • Very tight margins in link budget will challenge measurements • Tx output ...
