Time slots will be posted shortly by admin.
Topics are:
1) Transceiver design
2) Performance metrics, e.g., noise, distortion, linearity
3) Impedance matching
4) Passive filters
5) LNA/LNTAs
Note: Detailed questions on mixers and oscillators will not be asked specifically. However, as the topics overlap each other, be prepared to answer questions on ALL the subject matter covered in class. Good luck!
Oral exam is set for Friday 14. Topics and time slots will be posted shortly.
Be prepared to present and defend your work in a 15 min presentation on Wed. 5. We'll start at 10am.
Project submission: 12 am, Dec. 3
- Individual reports required
Project evaluation: 10 am, Dec. 5
- 15-20 min. individual evaluations
Exam: Dec. 14
- Oral or written - to be decided
Next week's there will be no lecture. Instead we will discuss any questions you may have wrt the final project, so come prepared! I do not want to be the one to do the talking. This is not going to be graded.
Note: each student must submit their own report (.pptx) of the final project, irrespective of whether the work is done as part of a group.
Final project grading: work individually or part of a group; that is up to you!
- Individual: 40%
- Group: 20% collective + 20% individual
Design requirements:
The first 2 blocks of a differential wideband direct-RF receiver - filter and LNA. The differential input impedance is 100 Ω. Assume we have 200 fF capacitance at each single-ended port (50 Ω) to ground. Optimise for power consumption. Justify all your choices!
Block 1: Passive single-harmonic trap HPF
Specs.: S11 < -10 dB, < 3 dB insertion loss, 7 GHz cut-off freq., Rejection required at 5.8 GHz is at least 10 dB. Rejection at 5.1 GHz > 20 dB. Choose the type of filter and order.
Block 2: Unconditionally stable wideband LNA

We will go over assignment 2 tomorrow. You do not have to hand it in.
Please submit your take on the problem by/before next week's lecture. Thanks, and have a good weekend.
Design a 50 Ω doubly termination BPF w/ lower and upper cut-off frequencies at 6 and 10 GHz, respectively, and at least 20 dB stopband attenuation at 500 MHz offset. Use TSMC's CMOS 90 nm process.
Choose the order and type of filter appropriately.
Hint: maximise Q of the passive components!
7th order elliptic LPF w/ 5.1 GHz stopband frequency, 40 dB stopband attenuation, and 0.1-0.5 dB passband ripple.
Use TSMC's CMOS 90 nm process. Plot magnitude and phase response, group delay, impulse response, 1dB compression point (optional). Explain/demonstrate the filter and reactive component(s) optimisation procedure. Explain amplifier/buffer (if required) design process, including biasing.
Hint: optimise passive components for highest Q!
Teacher is out traveling Tuesday 25/9. Students can use the class to run through Cadence tutorials or work on exercises together.
Some RF design examples may be found here:

Due to travel activities, there will be no lecture this week.
As this course has gone through a major revision since last year (INF5481), the textbook is new and was selected too late for Akademia to order it. Students therefore need to purchase it from other sources like here:
The first introductory lecture in IN5420 is held today.
