Functional verification is one of the key problems hindering successful design of large and complex hardware. As the base of functional verification, summary and decomposition of function points are leak-prone due to lack of standard language to abstract function points from specification. In this paper, we propose a function abstraction language, FAL, which is used for describing function points...
A filterless digital audio class-D amplifier (CDA) based on grow-Left double-edge (GLDE) pulse width modulation (PWM) is proposed in this paper. It consists of a high performance fully-digital uniform-sampling PWM (UPWM) modulator and a bridge-tied-load (BTL) power stage. Due to adopt the ternary PWM modulation scheme, the filterless solution without LC low-pass filter becomes possible. Finally, the...
This paper presents a low-power adaptive edge decision feedback equalizer (DFE) for 10 giga-bits-per-second (Gbps) serial links with 4 PAM (pulse-amplitude-modulation) signaling. Optimal tap coefficients are obtained adaptively using a sign-sign least-mean-square (SS-LMS) algorithm that minimizes the jitter of equalized data. Low-voltage-differential-signaling (LVDS) tap generators that double DFE...
