Piezoelements are typically used for vibration control and damping. The piezo ability for fast and very precise positioning has also found a main application in the synchronization of mode-locked lasers. Piezos in laser oscillators have a typical capacity of a few hundred nF. They can be controlled with voltages in a range of −20V to 120V specified for room temperature conditions. What is more, they...
In this article, an analog fully programmable membership function generator (MFG) is presented. It is capable of generating Gaussian, Triangular and Trapezoidal shapes as well as S or Z shapes. For omitting noise disturbances, differential structures are utilized in input and output stages which are in voltage mode and current mode, respectively. In contrast with conventional MFGs which are controlled...
A new technique to enhance single-stage operational transconductance amplifiers (OTAs) is presented. Enhanced DC gain and reduced input parasitic capacitances are achieved by employing two input fully-differential voltage combiners, i.e. a combination of transistors in common-drain and common-source configurations operating as a preamplifier stage. Simulation results show that the input capacitance...
Modern accelerator control systems based on MTCA.4 platform require femtosecond synchronization of RTM cards containing analog front-end electronics for high-speed digital signal processing AMC cards. The main challenge in such system was to realize distribution of few tens of high-quality RF signals to and between RTM cards with high reliability. Usage of coaxial cables with RF connectors in relatively...
