HW#6 – Check the online solutions for end–of–chapter problems for Ch. 26. Generate a better, and more correct, solution for any of the online solutions that aren't high–quality. Feel free to put your name on your solution. It will replace the existing solution if it's better, that is, clear and concise, due Wednesday, October 11
HW#5 – A26.1–A26.4, due Wednesday, October 4
HW#4 – Explain, in your own words, Correlated Double Sampling (CDS) and give an example of the use of CDS using LTspice (hint: use the flicker noise sims in the extras folder along with two switches, two capacitors, and a VCVS to show a change in the output noise spectrum), book problem 8.6 and verify your answer using LTspice, explain what happens to the output SNR when you integrate the output of the circuit seen in Fig. 8.29 (again, verify your answer using LTspice), A8.5, and A8.13, due Monday, October 2 

HW#3 – A8.1–A8.3, due Wednesday, September 20

HW#2 – A3.5, A3.8–A3.10 (from Ch3_MSD_hw.docx), due Wednesday, September 13

HW#1 A3.1–A.3.4 (from Ch3_MSD_hw.docx), due Wednesday, September 6

 

Course project – using On's C5 process (process information can be found at On's website, minimum L is 600 nm, SPICE models are found in C5_models.txt) design an analog front–end for converting current from an APD into an output voltage. Assume the APD has the structure seen here. The APD's cathode (n–well) will be connected to a 15 V DC supply (or whatever is needed for your design). The APD's anode (p+ in the n–well) will be connected to ground through a resistor. Determine, based upon the information you have, the value of the resistor and how it influences the biasing and noise performance (SNR). Assume the APD's depletion capacitance is negligible. Do you have to AC couple the APD's current into the analog front end or can the diode's bias current be DC connected to the front–end's input?

 

Your report should detail the design and evaluation of the following:

 
Your report should contain, at least, the following:

 

This is not a team effort. A PDF of your report and zipped-up simulation files are due (email to rjacobbaker@gmail.com) at 5 PM on Wednesday, November 29.
