    Springs and masses connected together in a line

    Homework Statement So there are 4 masses in a line. They are connected by 3 springs between them, denoted by k_12 & l_12 (spring coefficient + natural extension length), k_23 & l_23, etc. Homework Equations Write down the f = ma equations of motion for all 4 masses. The Attempt at...

    Control engineering: lead and lag compensators

    Not sure if this is the right forum, but I'm an electrical engineer studying controls so here goes. Here's my background on what I know. Lead or lag compensators generally have the form C(s) = K*(s+z)/(s+p), i.e. the controller has a DC gain and introduces a pole-zero pair. In the case of a...

    Why does the CMOS inverter operate in triode mode in static operation?

    thanks for the reply es1. So because the PMOS is on but not connected to any load we must have V_o = Vdd. I guess for the case of a parasitic capacitance from V_o to ground this doesn't affect the DC analysis either, thus keeping it in triode mode. I think I get it, thanks again.

    Why does the CMOS inverter operate in triode mode in static operation?

    Hello, I have a question about how to analyze the CMOS inverter (this circuit: http://www.cs.umass.edu/~weems/CmpSci635A/Lecture2/image10.gif ). Just to clarify, the input voltage is connected to both gates, and the PMOS on top has its source connected to Vdd. The NMOS on the bottom has its...
