| Abstract(in English) | This paper proposes a design of DC servo circuits which are used to suppress DC components in the outputs of amplifier circuits. So far, DC servo circuits are designed using a first-order non-inverting integrator in the feedback loop of amplifiers. The proposed design considers whole characteristics including amplifiers and DC servo circuits as highpass filters. This paper gives the design method of third-order DC servo circuits. New Bessel-based transfer functions are proposed by converting the Bessel lowpass filters in addition to the conventional lowpass-highpass transformation. LTspice simulation is given to show the effectiveness of the proposed method. |
