Final Project - Low-power front-end design
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
Spec.: Gain > 12 dB, NF < 3 dB, 7-10 GHz BW, and P1dB > -20 dBm. Capacitive loaded with 100 fF (differential).
Analysis: DC, AC, Noise, Transient, SP, PSS, PNoise, HB (LSSP)
Good luck (cause you'll need it) :)
