Op Amps

Attached is the problem and the work I've done so far. Please check to make sure it is absolutely correct and then help me understand and SOLVE the rest of the problem. **Any bottom of any circuit cutoff, it's just a horizontal line for ground w/ nothing else.

MOSFET amplifier w/active load

For a simple MOSFET amplifer with active load shown in Figure 1-.33, the transistor parameters are: Vtn=1v, Vtp1=Vtp2=-1V, Kp1=Kp2=Kn=100 uamps/V^2, and lambda1=lambda2=lambdan=.02V^-1. Let V+=10V and Iref=100 uAmps. (a) Find Vsg. (b) What value of Vi will produce Vds0=Vsd2? (c) determine the open circuit small signal gain. ...continues

Differential Amplifier Design

Please work the problem and explain how you found the necessary values. Thank you. Design a differential amplifier as shown in Figure 11.28 incorporating a basic two transistor current source to establish Iq. The bias voltages are V+=15V and V-=-15V, the transistor parameters are Beta=180 and Va=100V, and the maximum forwar ...continues

BiCMOS Diff-Amp

The BiCMOS circuit in Figure P11.57 is equivalent to a pnp bipolar transistor with an infinite input impedance. The bias current is Iq=900uA. The transistor parameters are :Kp=1ma/V^2, Vtp=-1V, and lambda=0 for M1; and Beta=100, Vbe(on)=.7, and Va=infinity for Q2. [a] Sketch the small-signal equivalent circuit (mine didn't wo ...continues

Derive the output equation for the instrumentation amplifier

How do I derive the output eqation for resistance? Is the Vx/Ix, if so, please walk me through the kvl or kcl so that I can see how to determine the output resistance. Thank you greatly.

Fourier Coefficient

Please work through attached problem and let me know how you did it. Thank you.

Fourier Xform help

Using tables and properties, calculate the Fourier transform for x(t)=(t^2)*(e^(-t/5))*(cos(3*pi*t)) I'm pulling my hair out with this problem. Please tell me which properties you used to calculate the Fourier transform for this equation. Tanks.

filter design

Considering x[n]=1+sin((3*pi*n)/8 + pi/4) + cos ((9*pi*n/24) + pi/4) , please design a filter that will pass the sine-wave portion, but ignore everything else. What is the filter's input response h(t)? In a real filter, what would you have to to differently? Thanks.
