how to calculate THD ??

Muffassir

 Hi all;

 

 I want to calculate the total harmonic distortion (%)   of my analog circuit.. I have two inputs as Vx and Vy ..Wherein i want to plot the THD variation due to input voltage swing between 0 and 1.8V while Vx set to different DC values.

How can i do that in cadence . I am using Cadence 6.1.4.500 and ADE L . and gpdk180.

 

Thanks in advance..

    How to measure THD and gain in cadence 5.10.41

    Hi Andrew
    Following the above post, I have a similar inquiry wherein I have a CMOS OTA and I have to plot its THD in Cadence Spectre.

    I have done parametric analysis in 5 frequency steps and then when I went to calculator and filled in all 4 parameters and clicked THD in special functions it simply gave me a scalar value.
    But I want to plot THD graph with 5 tones plus fundamental while calculator takes only one frequency at a time.

    Is there any other method of calculating THD without using calculator?

    Pl help....thanks
