D. Flandre et P. Jespers, CHARGE-SHEET MODELING OF MOS I-V FUNDAMENTAL NONLINEARITIES IN MOSFET-C CONTINUOUS-TIME FILTERS, Electronics Letters, 31(17), 1995, pp. 1419-1420
The linearity of the two-MOSFET and four-MOSFET integrators used in MO
SFET-C continuous-time filter implementations is compared using the ch
arge-sheet model. The results question the widely-accepted superiority
of the four-MOSFET structure in terms of higher attenuation of odd-or
der harmonic distortions.
