A novel receiver front-end is proposed for FM/FSK modulated signal, which is transmitted from a body worn device in the MedRadio spectrum of 401–406 MHz. The front-end comprises a low noise amplifier (LNA), a zero crossing detector (ZCD) and a frequency to digital converter (FDC). The proposed architecture offers direct digitization of the input signal and is immune to LO leakage and problem of image...
The Readout Integrated Circuit (ROIC) consists of charge integration, charge to voltage conversion, Pixel voltage multiplexing, signal transfer and amplification stage. The control circuit manages all the sequential events from charge integration to amplification stage. The large dynamic range requirement is the most challenging aspect in modern CMOS process. The infrared (IR) detectors looks for...
Repeaterless low swing interconnects are potential candidates for high speed low power signaling over on-chip global wires. Capacitive pre-emphasis at the transmitter has been shown to improve the achievable data rate by increasing the relative power at high frequencies. This paper shows an improved transmitter with a 1-tap feed-forward equalizer in addition to capacitive pre-emphasis. A design method...
