(a) Draw the equivalent circuit used for ac analysis of the circuit shown . (Use transistor symbols for this part.) Assume all capacitors have infinitevalue. (b) Redraw the ac equivalent circuit, replacing the transistor with its small-signal model. (c) Identify the function of each capacitor in thecircuit (bypass or coupling).
Modify this circuit to extend the upper frequency limit to greater than 15 MHz. You may change the topology (i.e. configuration), but not the power supply voltage or collector bias current. The circuit voltage gain must be 46dB +/- 1 dB. Provide simulation results to show AC frequency responses of both circuits on the same plot, and annotate the 3dB upper frequency limit on both traces. Use typical ẞ values from the data sheet for the simulation. You may assume that 1% resistors are available in values below 100. The circuit must adhere to Standard Bias techniques.

Figure Q5 shows the cross-section of the typical layout of two tracks (A and B) on a printed circuit board with a ground plane C. The tracks are terminated as shown in the figure, with track A carrying digital signals. You can assume that the lines are electrically short.

Hello, I got 0.79 for the firt part and 50A for the second part. And for the 3rd part is it triplens that add into the nuetral line for a 2phase system? I 'm hoping to see if I am doing it right. Not sure If I am. Thank you for the help.
A baseband signal has the spectrum sketched in the first image added below. The baseband signal modulates a 98 kHz carrier sine wave. Using frequency and amplitude labelling similar to that in Figure 2, sketch the spectrum of the modulated signal using a template added in image 2, for the following modulations: i-AM with the amplitude of the carrier wave being 20 V ii-DSBSC iii-SSB – the lower sideband iv-SSB – the upper sideband
Problem8) Determine the signal space representation of the four signals s(t), k = 1, 2, 3, 4, shown in Figure P3.2, by using as basis functions the orthonormal functions $1(t) and ø2(1).

This problem is AC analysis problem. DC analysis is not needed to answer the question. A) If we assume that the peak voltage of Vbe must be less than 10 mV to avoid small signal violations determine the value of Rsig if Vi has a peak amplitude of 1 V and Is = 1mA. Hint: Don't forget r!! Answer: Rsig =. B) If you did the DC analysis on this problem and calculated Vc = 50 mV and Vs = -100 mV what is the maximum amplitude of the output voltage while the circuit stays in active mode. Answer: Vo,max =, When you "verify" a mode of operation you will need to calculate all three voltages (Vc, Ve, VE for BJTS and VG, Vs, Vp for MOSFETS) and show the correct two conditions are satisfied. Assume Capacitors acts like open circuits at DC and short circuits for AC. > Assume the following: 5V o Beta = 100 O VBE = 0.7 o V: (Thermal) = 26 mV o Vr (Threshold) = 2V O VA = - o For MOSFET saturation mode: assume: lp = K(VGs-Vr)?
