Fractional-Order Phase Shifters with Constant Magnitude Frequency Responses
Original language description
This contribution presents and experimentally analyzes an idea how to reach constant magnitude as well as phase response in fractional-order (FO) phase shifting twoports. The straightforward method employing the automatic gain control circuit (AGC) in a cascade after so-called constant phase block approximating FO integrator or differentiator is studied. The variable gain amplifier utilized in AGC and simple RC-based FO constant phase elements (approximating capacitors with order alpha = 1/4 and 1/2 as an example) connected in the feedback of operational amplifier-based integrator are established in experimental setup. Operation indicated in three decades (between 100 Hz and 100 kHz) is evaluated. Known solutions of standard FO phase shifting circuits are discussed and generally compared with features obtained in this paper, together with supposed effects of AGC on their performances.
