The presented dissertation thesis deals with a novel structure of delta-sigma () modulator which compensates influence of higher harmonic distortion and therefore it is possible to achieve high resolution up to 16 bits. This novel proposed structure combines advantages of one bit quantizer modulators with mutli-bit modulators. The novel second order structure is presented, correct function is verified in MATLAB simulation enviroment and requirements for partial block are studied. The second part of the work deals with design of converter with novel structure of modulator using switched capacitor technique utilizing ONSemi I3T25 technology. Advantages and disadvantages of the novel structure are evaluated and novel structure is compared with common structures of modulators.
