Considerations about Frequency Spectrum and Signal Feedthrough in the Analysis of Switched-Current Filters
نویسنده
چکیده
The ASIZ program, written for the analysis of switchedcurrent filters, in the original version considered only the main spectral component of the output signal, and assumed sampled-and-held input signals. This paper describes the implementation in the program of full output spectrum computation and direct signal feedthrough effects. The extension is simple, since the semi-symbolic approach of the algorithm already computes all the required quantities.

New Clock-Feedthrough Compensation Scheme for Switched-Current Circuits - Circuits and Systems II: Analog and Digital Signal Processing, IEEE Transactions on
An improved clock-feedthrough compensation scheme for switched current system is proposed. Both the signal dependent and the constant clock-feedthrough terms are canceled by using both nMOS and pMOS current samplers and by adopting a source replication technique. The proposed current memory cell was fabricated with 0.6m CMOS process. Both experimental and theoretical results on clockfeedthrough...

This paper presents an efficient modeling and frequency domain analysis method for analyzing the effect of the clock feed-through and charge injection in switched current circuits. The effect of clock feedthrough is analyzed by modeling the clock signal using two constant voltage sources that are switched periodically. The charge injection is depicted using two impulse charge sources that injec...

متن کاملThe advantage of using a diode laser instead of a Q-switched laser in photoacoustic imaging of tissues
Photoacoustic (PA) imaging of biological tissues using laser diodes instead of conventional Q switched pulsed systems provides an attractive alternative for biomedical applications. However, the relatively low energy of laser diodes operating in the pulsed regime, results in generation of very weak acoustic waves, and low signal-to-noise ratio (SNR) of the detected signals. This problem can be ...
متن کاملA Time-Frequency approach for EEG signal segmentation
The record of human brain neural activities, namely electroencephalogram (EEG), is generally known as a non-stationary and nonlinear signal. In many applications, it is useful to divide the EEGs into segments within which the signals can be considered stationary. Combination of empirical mode decomposition (EMD) and Hilbert transform, called Hilbert-Huang transform (HHT), is a new and powerful ...
