            Abstract : 
For the original article see ibid., vol. 38, p. 456-461 (1991). In the aforementioned paper two configurations for realizing second-order voltage transfer functions using a single current conveyor (CCII) were given. The commenter points out that there is an error in the basic equation of the first configuration and gives a corrected version of the equation.
