Abstract :
In a recently published paper by K.R. Lakshmikumar, et al. (see ibid, vol.SC-21, no.6, p.1057-66, 1986) the yield of a digital-to-analog converter (DAC) as a function of component matching is estimated analytically. Here, an assumption inherent to that derivation, namely that the DAC outputs are independent, is questioned and is demonstrated to be inconsistent with Monte-Carlo simulations. The reply of the authors of the original paper is also included
