摘要

For the original article see ibid., vol.24, no.1, p.177-80 (1989). The commenter notes that the basic inverting SC differentiator described by C.-Y. Wu et al. was proposed by B.J. Hosticka and G. Moschytz (1979), and the behavior of the earlier circuit is discussed. The commenter also points out that the operational amplifiers in the SC filter of Wu et al. must slew in each phi /sub 1/ phase from the signal value to ground, thus limiting the maximum usable clock frequency.
