Abstract

The embodiment of the invention discloses a high-energy-efficiency equalizer architecture. The architecture comprises a filtering module which is used for filtering an input signal, a processing module which is connected with the filtering module, the processing module comprises a plurality of MOS tubes which are in complementary connection, and the processing module is used for transconductance amplification of a current signal of the input signal; and the architecture further comprises a conversion module which is connected with the processing module, and the conversion module is used for converting the current signal into a voltage signal. According to the high-energy-efficiency equalizer architecture provided by the embodiment of the invention, by accessing a complementary transconductance tube and using the same transconductance amplification stage current, double transconductance can be obtained, and meanwhile, the output transresistance stage can still keep constant bandwidth and gain, so that compared with a traditional linear equalizer architecture, the high-energy-efficiency equalizer architecture achieves the effects of high compensation capability and high driving capability.

Description

technical field [0001] Embodiments of the present invention relate to integrated circuit technology, and in particular to an energy-efficient equalizer architecture. Background technique [0002] When high-speed serial data is transmitted, due to the influence of non-ideal factors such as skin effect and dielectric loss, the high-frequency component of the signal is seriously attenuated, resulting in symbol distortion, which interferes with symbol judgment, that is, inter-symbol interference. The faster the data transmission rate, the more obvious the impact of intersymbol interference. In order to increase the channel bandwidth, a continuous time linear equalizer (Continuous Time Linear Equalizer, CTLE) needs to be used. Equalizer is a technology used to compensate signal transmission loss in communication systems, which can reverse signal distortion and improve eye diagram quality. Continuous Time Linear Equalizer (CTLE) is the core device of the receiving end (RX) of th...
