        Tunable High-Q N-Path Band-Pass Filters:
        Modeling and Verification
        
        Good introduction to N-path filters
        
        Bring the ~~comportamental~~ expalation of the behavior of the system, a VERY GOOD ONE, in time or freq. domain
        
        \( f_{s} \) controls the \( f_{c} \) and C controls the band
        
        Analysis of the transfer function, and state space analysis
        
        Clock signal must be less than \( \frac{1}{N} \)
        
        Development of a RLC equivalent model
        
        Noise Modeling
        
        Increasing switch size, improve linearity and \( r_{ON} \)
        
        Implementation of a 4-path diff filter (65nm)
        
        Power consuption (2 to 16) mW
        
        Voltage gain = -2dB
        
        Q = 3 to 29
        
        IIP3 = 14dBm
        
        NF = 3~5 dB

        Analysis and Design of I/Q Charge-Sharing
        Band-Pass-Filter for Superheterodyne Receivers
        
        A brief comparission between N-path and CS filters
        
        CS-BPF does not generate IM2 products
        
        A very didatic explanation of a DT IIR filter
        
        Explain the complex transfer function
        
        for freq. below \( \frac{f_s}{10} \) the CS-BPF can
        be modeled by a continous time model (RC)
        
        Heterodyne architecture probably have the IF freq.
        bellow \( \frac{f_s}{10} \), so, its a good model
        
        25% of duty-cycle provides better conversio gain
        and introduce less flicker noise.
        
        Justify the IF selection by the flicker noise corner
        
        Provides a excellent mismatch robustness
        
        Implementation Issues implement a notch response arround
        DC, so this topology is recommended for \( i_f \geqslant 30MHz \)

      - ADPLL
      - GFSK modulation scheme
- - - - the VCO normally operates at the double of the
        transmitting frequency, to reduce the injection pulling of the VCO when the PA starts-up. That's consume a lot of power.
