In this paper, a new compact, low power and low voltage structure for CMOS analog multiplier is proposed. All of them are implemented using a compact circuit. The circuit is designed and analyzed in 0.18µm CMOS process model. Simulation results for the circuit with a 1.2V single supply show that it consumes only 25µw quiescent power with 2GHz(More)
In this paper a new efficient fractal based compression algorithm is proposed for electrocardiogram signals. The self-similarities in the ECG signals make them suitable to be compressed efficiently using fractal based methods. In the proposed method, as in the basic fractal based compression method, each part of the signal is mapped to another part with a(More)
New analytical equations are proposed for oscillation amplitude of the MOS Colpitts oscillator. These equations are obtained from a large signal analysis. The analysis is based on a reasonable estimation for the output waveform. The estimated waveform should satisfy the nonlinear differential equations governing the circuit. The validity of the resulted(More)
In this paper, a new low voltage topology for analog multiplier is presented. The circuit can be used with single low-power supply. The complete circuit has only twelve transistors; therefore, it satisfies the need for compact sub-circuit in analog VLSI systems. The mathematical discussion on the power consumption, total harmonic distortion and other(More)
