Texas Instruments Explain Low-Dropout Linear Voltage Regulators

Today in power electronics, the folks over at Texas Instruments have put together a video covering low-dropout (LDO) linear regulators. For a hacker, power is pretty fundamental, so it behooves us ...

Maximum RF Input Signal on the Electro-Optic Modulator Transmission Boundary Area for Harmonic Distortion Compensation in Analog Radio Over Fiber

Abstract: In this study, we perform an analytical investigation of the electro-optic (EO), Mach-Zehnder modulator (MZM) transmission boundary area with a nonlinear model. We propose a nonlinear model ...
