Circuit Analysis & Design Contest


 IEEE SSCS 2021 International Student Circuit Contest 


The IEEE SSCS International Student Circuit Contest's objective is to engage students in thought-provoking circuit analysis and design problems. Submissions are solicited by both undergraduate and graduate students who are currently enrolled in a college or university. 


Please solve the following problem

Provide an example of an amplifier where, despite the presence of a positive feedback, the system cannot latch since the topology guarantees always a positive gain margin (regardless the components values or mismatches)? In your answer please clarify the expression of the loop gain and show that there is actually a positive feedback but the magnitude can never exceed one.

You must be an undergraduate or graduate student currently enrolled in a college or university to enter the contest. You do not have to be an SSCS member to submit to the contest, however, you must be an IEEE member. 

Please review the contest rules and regulations prior to submitting.

You must use the contest form to submit your answer to the problem. Email submissions will not be accepted. Please CLICK HERE for the form. 



The contest deadline is JUNE 30, 2021 at 12:00 AM EST. 



Up to three contestants with the best answers will receive US$2K each towards attending an SSCS-sponsored conference (ISSCC, CICC, ESSCIRC, VLSI Symp., ASSC). This award is paid either as a reimbursement following the attended conference or will be paid directly to the conference for registration and to the hotel for accommodations. All the submitters with the right answers will receive one year of free membership in the Solid-State Circuits Society, and their names will be highlighted in the Solid-State Circuits Magazine.
