A multiphase LC voltage-controlled oscillator (VCO) with a novel capacitive coupling CL ladder filter structure is proposed in this paper and this 10 GHz eight-phase VCO is applied in clock and data recovery (CDR) circuit for 40 Gb/s optical communications system. Compared with the traditional eight-phase oscillator, this capacitive coupling structure can(More)
Mobile health applications offer unique opportunities for monitoring patient progress, providing education materials to patients and family members, receiving personalized prompts and support, collecting ecologically valid data, and using self-management interventions when and where they are needed. Mobile health application services to mental illness have(More)
A 10 Gb/s continuous-time linear adaptive equalizer IC for 10 Gigabit short-reach optical interconnects using GLOBALFOUNDRIES (GF) 0.13 μm SiGe BiCMOS technology is described. The circuit consists of a continuous-time linear equalizer, an adaptation loop using spectrum balancing technique, an on-chip bandgap reference (BGR), and a low-dropout regulator(More)
This paper proposed a 4-channel parallel 40 Gb/s front-end amplifier (FEA) in optical receiver for parallel optical transmission system. A novel enhancement type regulated cascade (ETRGC) configuration with an active inductor is originated in this paper for the transimpedance amplifier to significantly increase the bandwidth. The technique of three-order(More)
