NPNs (at least in an "analog" process where they are a valued element and processing cares about mismatch) will tend to have a better natural matching in a smaller area than a nmosFET. You can do a chopped and filtered bandgap with good results, provided that you can tolerate a high output impedance and some chop-frequency residue. In a clocke
I am designing a charge pump for PLL. The structure is similar to traditional one which is: cascode pmos as up current, cascode nmos as down current, the middle is switch. The output voltage is from 0.4V to 1.4V as VDD=1.8V. If I want to get the DC current mismatch( (Iup-Idn)) less than 1% at output (...)
yeah I tried it and I got gain as expected Oh good! It's your lucky day then ;p If you look at your output stage, have you ever wondered who controls your output current? Basically, both the PMOS and nmos current mirrors are trying to force a current at the output. Device mismatch, short channel, systematic offs
SF/FS are not a montecarlo simulations but corners on the one case the nmos are slow an pmos are fast (all transistors on the simulated scheme) on the other case in revers the nmos transistors are fast and pmos are slow on the case of monte carlo mismatch simulation the different parameters changing randomly and not so critically like (...)
So, I have such a question. If we have simple bias circuit: two nmos, two PMOS, and rezistor between source of one of the nmos and ground. What is better nmos to be in weak invesrion or in
Dear all, I want to plot the nmos transistor drain current mismatch σ(ΔID/ID) versus effective gate voltage VG − VT curve by using hspice. How should I do? Example as shown below.
