Mathematica and Matlab differ on their aim, so youcan not choose one or another, if you want to perform symbolic analysis mathematica is a powerfull tool, but if you need to work with data matlab will solve everything you need.
To calculate the PSRR in a bandgap reference. Place a \[v_{ac}\] in series with \[V_{DD}\] and measure the gain, \[v_{ref}/v_{ac}\]. Next do the same with \[V_{SS}\].
The TC is the variation of a voltage, current, resistance, etc with the variation of the temperature, for example, the resistance raises as the temperature raises.
The TC is related with the bandgap cell because the variation its voltage must be very low as varies the temperature.
One way to...
Re: delay minimization
You have yo check the worst case in charge and discharge of the capacitance of each transistor in your inverter and modifie the gates in the transistors to minimize the capacitances
Re: Question about OP AMP
if the opamp is diferential input and single output, you can find negative input watching the gain polarization. if you increase input voltage in a terminal and the output decreases, you had found your negative input, and viceversa.
Re: Is there any rule for no. of contacts in case of MOS cap
the only rule i know about contacts is its size and distance, so if you don't brake this rule, you can add as much as tou want watching carefully the compromise low res vs capacitance
Re: analog HDL
i don't know how good is an analog cirtuit with describer language, but i prefer full-custom design
instead, can somebody with experience in that field, tell me how is the performance full-custom vs hdl description?
there are many ways to do a layout, and when u r in the industry you take what is already done, but, thas doesn't comes from wind, that is done for people like mazelk, so don't tell him "that is done", help him, and you shall learn how to get better performance in your layout
Re: Transistor as Resistors
you can biasing a current mirror with only add a diode-mode transistor, but, you have to add a start-up circuit because you can get a circuit with two answers, cero and your bias current. If you want to know more about self-biasing current mirror refer to Gray's book
