Abstract :
This paper deals with the design of high-performance OTA-C continuous-time filters. The fundamental limits of both noise level and Total Harmonic Distortion (THD) are further studied. In order to reduce the THD, several linear voltage to current transducers are discussed. These techniques allow the design high-performance filters; e.g. -60 dB total harmonic distortion for input signals up to 2 volts peak to peak. Experimental results are reported
