Energy Efficient Tunable Spectral Analysis for Built in Testing and Calibration Approaches
Journal Title: International Journal of Engineering Sciences & Research Technology - Year 30, Vol 3, Issue 11
Abstract
The Fast Fourier Transforms method for on –chip spectral analysis of multitone signals are used for particular harmonic and intermodulation components .The Fast Fourier analysis is based on coherent sampling it uses only small number of FFT points to make realization more suitable for on chip built in testing and calibration approaches that requires area and power efficiency.When on chip spectral analysis were used the linearity of analog circuits limits the signal quality in many wireless device in which the receiver circuits are integrated into a single chip. The Tunable spectral style approaches area unit need to live to and calibrate the one dimensionality of analog /RF circuits which varies from device to device. This is used to evaluate the linearity of analog circuits for performance optimizations and reliability improvements through the use of on-chip digital processing resources.
