چکیده
This paper presents a quad-channel 1.25-10.3125 Gbps wireline transceiver implemented in 40 nm CMOS technology. The transmitter consists of bit width adjustment, 40:2 multiplexer, 2:1multiplexer, and current-mode logic driver with 3-tap feedforward equalizer. receiver has two-stage continuous-time linear equalizer, 2-tap half-rate fully adaptive decision-feedback phase interpolation-based digital clock data recovery (CDR) followed by 2:40 demultiplexer, adaption. also supports AC/DC coupling, CDR locking detection, PLL loss signal automatic termination impedance calibration. A ring VCO-based is designed each lane to save power consumption, dual-core LC bank generate low jitter signal. At 10.3125 Gbps, the can equalize 28 dB Nyquist at error rate 10 -12 , it consumes 114 mW 1.1 V supply. work high efficiency 11.05 mW/Gbps, suitable for multi-standard applications due its flexibility efficiency.

A 1-Tap 40-Gbps Look-ahead Decision Feedback Equalizer in 0.18μm SiGe BiCMOS Technology
This paper describes a fully-differential 1-Tap decision feedback equalizer (DFE) in 0.18μm SiGe BiCMOS technology. The circuit is capable of equalizing NRZ data up to 40 Gbps. A look-ahead architecture is used with modifications to reduce complexity in the high speed clock distribution. An analog differential voltage controls the tap weights. The design is fabricated in 0.18μm SiGe BiCMOS tech...

A new architecture for digital implementation of the adaptive equalizer in Class IV Partial Response Maximum Likelihood (PRML) channels employing parallelism and pipelining is described. The architecture was used in a prototype integrated circuit in a 1.2 pm CMOS technology to implement a 50 MHz adaptive equalizer and Viterbi sequence detector dissipating 70 mW from a 3.3 V supply. 1 .O Introdu...

We develop a TAP mean eld approach to models with quadratic interactions which does not assume a speciic randomness of the couplings but rather adapts to the concrete data. The method is based on an extra set of mean eld equations for the Onsager correction term to the naive mean eld result. We present applications for the Hoppeld model and for a Bayesian classiier. 1.1 Introduction Mean eld (M...

Dr. Greg Hinson is in the minority. He's among the meager 13 percent of physicians in solo practice who use electronic medical records, according to a recent Commonwealth Fund survey. But Hinson is comfortable being apart from the madding crowd. He knew electronic record keeping would be the ticket to efficiencies in his practice so he traded in his hodgepodge of inadequate record-keeping techn...
