Abstract :
In the design of integrated continuous-time filters it is often difficult to choose a proper integrator circuit because the relative merits of the different possibilities are little known. A thorough analysis of all the possible circuits is necessary. In this work, the design and an accurate analysis of the noise and distortion properties of one type of integrator, based on a tunable bipolar transconductor, are given. The analysis is used to optimize the dynamic range, and the results are verified by simulation and measurement. A fifth-order low-pass filter design and implementation are presented to illustrate the usefulness of the designed integrator
