Homework Answers
(1). The curve which best represents ic vs vbe for the BJT is curve A. For a BJT the voltage vbe corresponds to a diode between the base and emitter terminal which under forward biased condition provides a constant voltage for any rise of output current ic .
(2). The curve which best represents ic vs vce for the BJT is curve C. the plot of ic vs vce is the output characteristics of a BJT which is ell depicted in curve C.
(3). The small signal transconductance is equal to the slope of curve B. Curve B is a straight line which has a slope of i/v which is equal to transconductance.
(4). The impact of base width modulation is visible in curve C. For an ideal BJT the output characteristics is a constant straight line parallel to the x-axis but with base width modulation an increasing slope is observed in the characteristics which is well depicted in curve C

plot best describes the impedance due to:
a. A Resistor
b. A Capacitor
PART 1: IMPEDANCE OF A CAPACITOR PREPARATION In an AC circuit capacitors and inductors have an effective resistance that restricts the flow of current, this is known as impedance. An equivalent to Ohm's law can be written where resistance R is replaced by the impedance Z: V = 12 (9-4) where V and I are either...

Problem 3: Design Problem On Figure P3a, you have a Common Source (CS) n-channel MOSFET amplifier. Notice the absence of a source resistor Rsig and load resistor R. If we know how the present amplifier (the one on Figure P3a) behaves without Rsig and RL, we can infer its behaviors if Rsig and R were to be added. design the amplifier circuit on Figure P3a, i.e., you have to find appropriate values for RGj You are to RG,, RD, and...

I need help answering questions 1-6 please Your group is working to develop and study new proteins. To analyze the composition of a protein mixture you have produced, the protein solution is placed in an electric field. Proteins with different total charges will drift at different speeds in the solution, and can be separated for further analysis. Your group needs to focus an optical apparatus at known positions within the protein solution in order to record an image of a...
