This work presents a first common gate continuous time linear equalizer (CG-CTLE) with charge mode adaptation in 1.1 V, 65 nm CMOS technology. The proposed equalizer is realized with a common gate topology and offers an input impedance of 50 Ω. It also acts as a first stage of current modereceiver and is made adaptive to varying channel loss. Therefore, the need for an external...
In this work we propose a power-efficient 4-PAM current-mode transmitter for high-speed chip-to-chip data communication applications. The proposed transmitter meets the impedance requirements of current-mode communication. It offers high output impedance for outbound signal, a requirement of a current-mode transmitter and simultaneously provides back impedance of 100-Ω differential for reflections...
In this paper we propose current-mode echo cancellation technique for full-duplex chip-to-chip data communication. A new hybrid circuit topology suitable for current-mode echo cancellation is presented. The hybrid circuit topology is shared integration of an operational transconductance amplifier(OTA) and a transimpedance amplifier(TIA). The output/back-port impedance of the hybrid is matched with...
In this work we propose self-termination scheme for high-speed current-mode differential signaling. This scheme eliminates the need of any dedicated passive terminator avoiding signal reflection both at the transmitter and receiver. We present fully differential, high speed transmitter/receiver(Tx/Rx) pair suitable for this self-terminated differential current-mode signaling scheme. We propose high-speed,...
In this work we propose an active termination scheme at the receiver-end for high-speed current-mode differential signaling. This scheme eliminates the need of any dedicated passive terminator avoiding signal reflection. Elimination of the terminator helps to reduce the transmitted signal level without effecting signal detect-ability of the receiver and also removes the thermal noise of the passive...
In this work we propose high-speed low-current duobinary signaling scheme over an active terminated chip-to-chip interconnect. The active termination scheme eliminates the need of any dedicated passive terminator both at the transmitter and receiver, avoiding signal reflection. Elimination of the passive terminator helps to reduce the transmitted signal level without effecting signal detect-ability...
