Abstract: Exemplary embodiments of the present invention relate to an output waveform synthesizer using phase interpolators and an on-chip eye opening monitoring (EOM) circuit for a low-power transmitter. In order to achieve both small area and low-power consumption in the transmitter design, a single-stage multiphase multiplexer operating in subrate is employed. The multiphase multiplexer is composed of parallelized open-drain NAND gates. In subrate transmitter architecture, the phase mismatch among multiphase clock signals degrades jitter performance significantly and is a critical bottleneck for its widespread use despite low power consumption. In order to overcome such mismatch problem, an area-and-power-efficient phase interpolator based waveform synthesizing scheme is developed.

Abstract: The proposed invention is about an improved method for serial-in and serial-out transceiver applications. The proposed system includes a dual loop phase locked loop (PLL) architecture having a PLL and a phase rotator (PR)-based delay locked loop (DLL). An advantage of this architecture is that a single PLL offers decoupled bandwidths; a wide jitter-tolerance (JTOL) bandwidth for receiving data and a narrow jitter transfer (JTRAN) bandwidth for the data transmission. Thus, the amount of jitter at the output can be substantially reduced relative to the input while offering sufficient jitter tracking bandwidth. Also, this architecture is suitable for low-power applications since a phase shifter in the data path, which is one of the most power-hungry blocks in conventional DPLL designs, is not required.

Abstract: A variable-precision distributed arithmetic (VPDA) multi-input multi-output (MIMO) equalizer is presented to reduce the size and dynamic power of 112 Gbps dual-polarization quadrature phase-shift-keying (DP-QPSK) coherent optical communication receivers. The VPDA MIMO equalizer compensates for channel dispersion as well as various non-idealities of a time-interleaved successive approximation register (SAR) based analog-to-digital converter (ADC) simultaneously by using a least mean square (LMS) algorithm. As a result, area-hungry analog domain calibration circuits are not required. In addition, the VPDA MIMO equalizer achieves 45% dynamic power reduction over conventional finite impulse response (FIR) to equalizers by utilizing the minimum required resolution for the equalization of each dispersed symbol.

The proposed system shows an over 2× increment in the figure of merit (FOM) compared to conventional designs. Experimental results support the validity of the proposed system.
