This analytical and graphical technique allows engineers to determine, in closed form, the output of an RC filter driven by a PWM pulse train. It is based on the principle that current and voltage ...
Active filters are ubiquitous in electronic design today, performing signal-frequency manipulation and conditioning for audio, IF (intermediate frequency), and digital-signal processing. The success ...
What do you really get using a supplier tool for an multiple feedback (MFB) low pass active filter? Let's continue the quest for the best results using the example designs from Part 1. In this online ...
This article is part of the Ideas for Design Series: Vol. 3, No. 9. Many communications and sensor applications require a bandpass filter with wide bandwidth. This filter typically requires precision ...
假設 $x(t) = e^{j \Omega t}$ ： $$ y_p(t) = H(\Omega) e^{j \Omega t} \tag{1-8} $$ 先求 $H(\Omega)$ ： 將 $x(t) = e^{j \Omega t}$ 和 $y_p(t) = H(\Omega) e^{j ...
Abstract: Single-stage operational transconductance amplifier is proposed for OTA-RC filter design. The concept is developed from a resistive source-degeneration long-tail pair where large ...
Abstract: An ultra low-power low-voltage active-RC filter design with on-chip automatic tuning system is presented. It is based on the compensation method for compact low-gain amplifier and can be ...
