comb generator by using srd
I am not sure whether i can explain well.. Comb generator... Let assume that the Comb generator is a box... If i input a signal with frequency, of F1 Hz into the box, the output of the box should give me, a signal at 1 x F1 Hz, a signal at 2 x F1 Hz, a signal at 3 x F1 Hz, a signal at 4 x F1 Hz, ....... all the way until N x F1 Hz. Of course, as it goes higher harmonic, the signal will become weaker. Hence if you can imagine, at every harmonic, there will be an impulse, that's where you can see the "comb" shape at frequency domain. My objective is to design the comb generator with minimum conversion loss.
SRD, step impedance diode, are use to generate pulses rich in harmonics. Since we are input an AC signal. During "+" cycle, the diode will store charge. During "-" cycle, charge is extract. Due to this effect, current pulse (with rise time = snap time of the diode) is generated when an inductor is connected in serie with diode. In frequency domain, it will appear like a "comb" signal.
Pardon me if my explaination is poor and correct me if i am wrong, i'm still learning.
