Analog VLSI Implement at ions of Continuous-Time Memory Structures

چکیده
The continuous-time implementation of the popular transversal filter is problematic since it is impossible to implement an ideal time delay in continuous-time hardware. We believe that building an ideal time delay would not be worthwhile anyway since the ideal time delay has shown to be inferior to low-pass (Gamma) and all-pass (Laguerre) stages in discrete-time simulations. We demonstrate feedforward analog VLSI implementations of the Gamma and Laguerre memory structures and show measurements of their performance. We also show through simulation of a system identification problem that the Laguerre filter is expected to converge faster and be more robust to the noise and offsets that we expect in an analog VLSI implementation.

متن کاملAnalog Hardware Implementationof Continuous - Time Adaptive Filter
We have implemented a four-tap adaptive lter in a continuous-time analog VLSI circuit. Since an ideal delay is impossible to implement in continuous-time hardware, we implemented the delay line as a cascade of low-pass lters (called the gamma lter). Since many years of research in our lab has shown that the gamma lter outperforms the ideal delay line for a wide range of applications, the gamma ...

متن کاملAn Analog Vlsi Circuit Implementing an Orthogonal Continuous Wavelet Transform
We have developed the theory and analog hardware implement-ation for a Cont.inuous Wavelet Transform (CWT). This novel circuit performs an orthogonal decomposition of temporal signals, such as speech, in a frequency range of IOHz to 20KHz. This multiresolution processor expands the Laguerre structure originally developed by Lee [4].
