    PTPX Switching power calculation

    How does PTPX calculate switching power. When I do get_attribute [get_cells $cellname] switching_power I get a value. How does the tool arrives at this value. report_power_calculation gives the leakage and internal calc but not switching. I am well aware of the formula 1/2 CV2 FA I quueryed...

    Techniques to reduce delays

    What are the different techniques to reduce gate delays and combinational logic circuit delays? I am aware of adding buffers to reduce circuit delays and sizing by the method of logical effort to reduce gate delays. What are the other techniques used by designers in the industry?

    Latch data maintain problem

    How do I even begin solving this:

    Cadence Ruler Thickness

    So I know how to manipulate the ruler, I changed the thickness and colour using hlite drawing 4. But the values of the distances are too thin. Can I somehow make them thicker too?

    Kirchoff's current law example

    I have a hard time understanding how kcl is applied to the following circuit: How is the RHS (gm1)Vin. Also, why is i0 equal to (Vs)/(Rss/2)

    Mealy state machine.

    Not really. Mealy state machine for detecting "10001" will have 5 different states. You only have two A and B.

    Calculating Vout/Vin of a circuit

    Is this right? Man, I **** at this

    Calculating Vout/Vin of a circuit

    Rs is actually Rg. If Ig is zero then Vout/vin = infinity. Doesn't make sense.

    Calculating Vout/Vin of a circuit

    I still have an unknown Ig.

    Kirchoff's current law applied to a circuit

    I am having a hard time understanding the equation the author derives from the figure: Why is current through r01 (Vgs2+Vgs1)/R01. Also, how is the equation in the middle derived.

    Calculating Vout/Vin of a circuit

    I did replace the mosfet with the small signal model but I can't solve it for Vout/Vin.

    Calculating Vout/Vin of a circuit

    How do I calculate Vout/Vin of this arrangement: I have to do this using the small signal model, I am a beginner level electronics student so a complete explanation would be nice.

    Calculating output resistance

    I tried calculating the output resistance of both the cases but got both of them wrong. For the left one: Since it is a common source amplifier: (1+gm*r0)rs+r0 gm= gm1 r0= (1/Gm3||ro3||ro1) rs= ro2 Can anyone tell me where exactly am I going wrong

    [moved] NMOS amplifier design, parameters given

    Re: NMOS amplifier design, parameters given Ok, but how do I design it. It is a very basic question I know

    [moved] NMOS amplifier design, parameters given

    How do I design an nmos circuit ( with no resistors) given that the drain to source current is 40 microamps and Vds is fixed at 1 V. Having a hard time figuring out whether I need to apply the formula for saturation or linear region.
