N2 - This paper proposes a novel 32Gb/s high-compensation hybrid five-stage stochastic continuous-time linear equalizer (CTLE) adaptation receiver for a 12-nm FinFET process. The innovative stochastic CTLE receiver, featuring a mid-frequency peaking structure, effectively addresses issues related to signal transmission characteristics, such as intersymbol interference (ISI). An attenuator (ATT) within the five-stage cascade circuit establishes a feedback system for the control system's common mode points, enabling low-frequency attenuation and effective modulation of low-frequency signals. Furthermore, a gain-tuning scheme combining ATT and CTLE is proposed and analyzed. This scheme implements a multi-stage equalizer with an adaptive equalization loop, providing a maximum peak gain between 35.45dB and 44.41dB at the Nyquist frequency. In comparison to other receivers of similar nature, this CTLE receiver exhibits a 32% enhancement in gain performance, achieving maximum horizontal eye margin. It boasts an adaptive convergence time of 3.3 μs and a total power consumption of 13.5 mW, all within an overall layout area of 0.01
