摘要: This paper presents the design of sampled analog wavelet processor architecture for cochlear implant application using discrete Haar transform. Basic element is operational amplifier based switched capacitor integrator circuit. distributes input signal frequencies into different predefined frequency band and on sensitivity region by arbitrary tree structure. The presented beneficial in terms processing time signal, area complexity avoiding quantization encoding process part data converter circuits. Simulation results this carried out with CMOS 90 nm technology.
