LSIs for digital signal processing

The authors describe high-performance CMOS LSIs for digital signal-processing (DSP) technology, such as digital filter, fast Fourier transform (FFT), discrete Fourier transform (DFT), and digital phase-locked loop (DPLL), for communication use. Device design for high-speed and low-power CMOS is described and its feasibility is shown as characteristics of propagation delay time and power delay product.
