    Calibre PEX problems

    hello all I am doing calibre pex in cadence working enviornment bt while doing inductance extraction following errror is coming ERROR: SVRF layer physical information could not be built. ERROR:The inputs for the inductance engine were not properly built. I surf the net regarding the problem wht...

    process_corners_analysis

    hello everyone i have designed LNA to be operating at 2.45GHz . i run the simulation on typical corners and results were coming good. But when i ran process corners it got fail at two values typically rather than tuning to 2.45GHz the circuit get tuned to 2.55GHz. now i am planning to redesign...

    1dB compression point_interpretation

    Thanks a lot jiripolivka, with further correction to my circuit I have again done the pss analysis and upto -25dBm my largte signal gain and noise figure remained constant. and when i plotted 1dB compression point by taking input power extrapolation point taking as -25dBm it come out to be...

    differential_low_noise_amplifier

    For Goldsmith, sir as for any differential amplifier we need one input to be inverted but in case of low noise amplifier we gives inputs at the port in terms of power ( input power handling capacity that is say -20dBm). I am giving one input as -20dBm but confused how to give input power for...

    differential_low_noise_amplifier

    hello everyone, i am trying to design differential LNA but to start with design i m facing problem however it is a stupid question to ask but i m confused how to use ports for two inputs specifically how to give inverted signal for the second input using psine source. pls help

    1dB compression point_interpretation

    Thanks a lot jiripolivka, but i extract is that the maximum signal level that can be tolerate by my amplifier is around -40dBm.So if i specify that my input referred compression point is -51dBm for -40dBm is this makes sense if i talk about linearity. or to i have to go above -40dBm with my circuit

    1dB compression point_interpretation

    Hello everyone, i have studied that for a linear system output power should follow the input power. But due to the large signals levels outputs get saturated and the point where the gain drops by 1dB is said to be 1dB compression point. I have plotted the output power vs input power...
