Analog VLSI Implementations of Auditory Wavelet Transforms Using Switched-Capacitor Circuits

Lin, Jyhfong; Pati, Yagyensh; Edwards, Thomas; Shamma, Shihab (1992)

A general scheme for the VLSI implementation of auditory wavelet transforms is proposed using switched-capacitor (SC) circuits. SC circuits are well suited for this application since the dilation constant across different ...

Area-Efficient Switched Capacitor Filters: Very Large Time- Constant Circuits

Lin, Jyhfong; Edwards, Thomas; Shamma, Shihab (1992)

The detailed theoretical analysis of very large time-constant (VLT) integrators which use either charge elimination (T-cell and Huang's integrators) or charge cancellation (Nagaraj's and charge-differencing integrators) ...

Area-Efficient Switched Capacitor Non-Filtering Circuits: Sum- Gain Amplifiers

Lin, Jyhfong; Edwards, Thomas; Shamma, Shihab (1992)

Switched-capacitor rum-gain amplifier (SGAs) are widely used in parallel filter systems. The capacitance spread of such circuits is proportional to the coefficient spread, thus making conventional SGAs unsuitable for high ...

Cochlear Filters Design Using a Parallel Dilating-Biquad Switched-Capacitor Filter Bank

Lin, Jyhfong; Ki, Wing-Hung; Thompson, K.E.; Shamma, S. (1991)

A parallel filter bank is proposed to implement cochlear filters using very large time-constant (VLT) switched-capacitor (SC) filters. Significant hardware reduction is achieved in three ways. First, VLT SC biquads are ...

Realization of Cochlear Model by VLT Switched-Capacitor Filter Biquads

Lin, Jyhfong; Ki, Wing-Hung; Thompson, K.E.; Shamma, S. (1991)

We describe here the realization of a cochlear model using switched capacitor filters (SCF). This approach is made possible by a new design technique, called charge differencing (CD), which reduces by up to 50% the silicon ...
