چکیده
We have developed an amplifier which removes its "offset" as a natural part of its operation by modifying the charge on a floating gate. The charge on the floating gate is adapted by a combinat,ion of electron tunneling and hot-electron injection, resulting in a nonlinear high-pass filter with a cutoff frequency less than 1 Hz. We show experimental data from this autozeroing amplifier for various input waveforms, and an analytical model which fits the output waveforms. This autozeroing amplifier is a single-input case of a continuous learning circuit.

متن کاملAn Autozeroing Floating-Gate Amplifier
We have developed a bandpass floating-gate amplifier that uses tunneling and pFET hot-electron injection to set its dc operating point adaptively. Because the hot-electron injection is an inherent part of the pFET’s behavior, we obtain this adaptation with no additional circuitry. Because the gate currents are small, the circuit exhibits a high-pass characteristic with a cutoff frequency less t...
متن کاملPITCH DETERMINATION AND SPEECH SEGMENTATION USING THE DISCRETE WAVELET TRANSFORM - Circuits and Systems, 1996., ISCAS '96, 'Connecting the World'., 1996 IEEE International Symposium
Pitch determination and speech segmentation are two important parts of speech recognition and speech processing in general. This paper proposes a time-based event detection method for finding the pitch period of a speech signal. Based on the discrete wavelet transform, it detects voiced speech, which is local in frequency, and determines the pitch period. This method is computationally inexpens...
متن کاملCOMPUTING THE GENERIC INDEX OF THE CIRCUIT EQUATIONS OF LINEAR ACTIVE NETWORKS - Circuits and Systems, 1996., ISCAS '96, 'Connecting the World'., 1996 IEEE International Symposium
In many problems, such as the analysis of electrical circuits, one has to deal with Differential-Algebraic Equations (DAE’s). Knowing their generic index is of interest for practical and numerical as well as for theoretical reasons. In this paper we give an algorithm that determines the generic index of the Circuit Equations of linear active electrical networks in polynomial time from tlie netw...
متن کاملDesign of Cascade-Form IIR Filters with Powers-of-Two Coefficients Using Mixed Integer Linear Progra - Circuits and Systems, 1996., ISCAS '96, 'Connecting the World'., 1996 IEEE International Symposium
We propose an optimal design method for digital IIR filters with powers-of-two coefficients. This method is based upon the formulation of a linear optimization problem that minimizes filter’s complexity for given specifications. It is shown that by taking the logarithm to the transfer function of cascade-form IIR filters, the design problem becomes linear and can be solved by mixed integer line...
