Systematic Design of a Transimpedance Amplifier With Specified Electromagnetic Out-of-Band Interference Behavior
Publication Year: 2010, Page(s):530 - 538
Cited by: Papers (3)In negative-feedback amplifier design, electromagnetic interference (EMI) behavior is usually completely disregarded. EMI can, e.g., result in detection of low-frequency envelope variations of the usually high-frequency interfering signals. If the detected signals end up in the pass band of the negative-feedback amplifier, they cannot be distinguished from the intended signal any longer, so the si... View full abstract»

Transient Charge Feedforward Driver for High-Speed Current-Mode Data Driving in Active-Matrix OLED Displays
Publication Year: 2010, Page(s):539 - 547
Cited by: Papers (7)A transient charge feedforward driver (TCFD) is presented for high-speed current-mode data driving in active-matrix organic LED (AMOLED) displays. In order to provide charging current for the parasitic capacitance of a column line (CL), TCFD adaptively generates the required charging current by taking advantage of the parasitic capacitance of another adjacent CL. The TCFD can dramatically enhance ... View full abstract»

Time-to-Digital Converter for Frequency Synthesis Based on a Digital Bang-Bang DLL
Publication Year: 2010, Page(s):548 - 555
Cited by: Papers (39)This paper presents the design of a time-to-digital converter (TDC) suitable for a 3.5-GHz all-digital phase-lock loop (PLL). The converter is based on a digital bang-bang delay-lock loop, which allows constant resolution over process and temperatures spreads, avoids an off-chip filter and guarantees fast lock. The clock rate of the digital filter is scaled down by eight from the 3.5-GHz input to ... View full abstract»

Calibration and Characterization of Self-Powered Floating-Gate Usage Monitor With Single Electron per Second Operational Limit
Publication Year: 2010, Page(s):556 - 567
Cited by: Papers (31)Self-powered monitoring refers to a signal processing technique where the computational power is harvested directly from the signal being monitored. In this paper, we present the design and calibration of a CMOS event counter for long-term, self-powered mechanical usage monitoring. The counter exploits a log-linear response of the hot-electron injection process on a floating-gate transistor when b... View full abstract»

To efficiently reduce power consumption, a novel dynamic-range detector is developed to dynamically detect the effective dynamic ranges of two input operands. The detection result is used to not only pick the opera... View full abstract»

High-Throughput Interpolation Architecture for Algebraic Soft-Decision Reed–Solomon Decoding
Publication Year: 2010, Page(s):581 - 591
Cited by: Papers (8)Reed-Solomon (RS) codes are used as error-correcting codes in numerous digital communication and storage systems. Algebraic soft-decision decoding (ASD) of RS codes can achieve substantial coding gain with polynomial complexity. Among practical ASD algorithms, the iterative bit-level generalized minimum distance (BGMD) decoding can achieve similar or higher coding gain with lower complexity. The i... View full abstract»

Publication Year: 2010, Page(s):592 - 603
Cited by: Papers (25) | Patents (1)Distributed arithmetic (DA)-based computation is popular for its potential for efficient memory-based implementation of finite impulse response (FIR) filter where the filter outputs are computed as inner-product of input-sample vectors and filter-coefficient vector. In this paper, however, we show that the look-up-table (LUT)-multiplier-based approach, where the memory elements store all th... View full abstract»

Observer-Controller Digital PLL
Publication Year: 2010, Page(s):631 - 641
Cited by: Papers (11)A digital phase-locked loop (DPLL) has been recently developed to exploit the increasing transistor speed of modern process technology. By employing a digitally controlled oscillator (DCO) and a time-to-digital converter (TDC), the loop filter of a DPLL becomes all-digital. Instead of designing the loop filter by digitizing a continuous-time loop response as has been commonly done, more sophistica... View full abstract»

The Spectrum of a Noisy Free-Running Oscillator Explained by Random Frequency Pulling
Publication Year: 2010, Page(s):642 - 653
Cited by: Papers (21)We show that the Lorentzian spectrum of a free-running LC oscillator arises from the random pulling of its frequency by circuit noise sources. To prove this, we analyze the oscillator's spectrum using Adler's differential equation, first in response to pulling by a single injected tone and then by two tones mirrored around the free-run frequency. A novel analysis predicts the frequencies and ampli... View full abstract»
