Peaking current source
WebThe peak current is the maximum amount of current which output is capable of sourcing for brief periods of time. When a power supply or an electrical device is first turned on, high initial current flows into the load, starting at zero and rising until it reaches a peak value, known as the peak current. WebJan 3, 2010 · peak current source to: Ghitani I think Q1 works in soft saturation region [1], the transistor is ok. to: Tangos The ckt you refered is a current source, it's an improved version of Delta-VBE current source [2]. but i don't know the ckt's name. to: sunking vbe=VT*ln (Ic/Is),

http://web.mit.edu/Magic/Public/papers/01470977.pdf WebThis startup circuit is also used for the other two self-biasing MOS current sources. The impact of NMOS threshold voltage variation on circuit performance is verified by simulation. (ii) The second one is a peaking current source (or a Nagata current source) with self-biasing configuration.
WebFor current-mode control there are three things to consider: 1. Current-mode operation. An ideal current-mode converter is only dependent on the dc or average inductor current. The … WebRemembering back to Chapter 11 Section 10 where we discussed the Peaking Current source, we have a circuit block that has such a positive temperature drift. We referred to this as a PTAT or Proportional To Absolute Temperature current.
