Engineering & Architecture Engineering (Mechanical / Chemical / Civil / Electrical)

This is a project. do all part and make a professional report. please lock at #Requirements

[

Part 1: Passive filter 

• Design a SE-SE high-pass filter to ‘capture’ 8 GHz wanted signal 

• Input and output port impedances: 50 Ω in parallel w/ 200 fF capacitance 

• ESD and pad model 

• Insertion loss/NF < 4 dB 

• In-band ripple <1 dB 

• Rejection at 6.425 GHz > 5 dB 

• Rejection at 5.8 GHz > 15 dB 

• Rejection at 5.1 GHz > 20 dB


Part 2: Amplifier

• Design a SE-SE multi-band low-noise amplifier (LNA) for 8 GHz

• Run dc, sp, trans, pss/hb, lssp, etc.

• Use of a transformer à bonus points!

• Specifications:

• Match to 50 Ω at the input w/ shunt parasitic capacitance of 50 fF (i.e., S_11 < -10 dB)

• S_21 > 15 dB

• Reverse isolation > 30 dB

• NF < 5 dB

• P1dB – max. achievable

• Power supply 1.2 V (nominal) 



#Requirements

• Draw schematic incl. interconnects

• Discuss design trade-offs!

• Provide detail (e.g., inductance and capacitance values of the components, length, width, L, C of the interconnects, area of each sub-block)

• Table of specifications and results

• Add graphs (e.g., S_21 (dB20 and phase) and S_11 (dB20), NF and group delay)

• Add graphs of inductor parameters (e.g., r_s, L, Q and self-resonance

frequency) for chosen dimension
