Hi all,
I'm trying to design a digitally buck controller with a direct form I IIR filter in a fixed-point representation, it works but I see small limit cycles.
Vin is 12V and Vout 3.3V, buck complex conjugate poles are at 15kHz and bandwidth and switching frequency is 1MHz.
I'm using type...
Z0 of connections (pcb traces and cable) is one of those things that can be arbitrarily varied within certain limits, while source and load impedance are fixed. Taking Rdson is correct if the silicon device productor declare VHF square wave operation and specifies minimum dv/dt output at various...
Just to clarify, it's not absolute high impedance but at resonance frequency minimum impedance of transducer is ten to a hundred times the source impedance, source impedance (Rdson) is low to maximize voltage transfer to the load (pzt require high voltage) and to charge the parallel c0...
let's suppose we have a fixed low-impedance source and a fixed high-impedance load with the purpose of maximum voltage transfer, to be connected each others by a long transmission line compared to wavelength of signal transmitted and we want minimal distortion caused by reflections. Is it a...
