Abstract :
It is shown that the simple three-phase wave generator presented by V.P. Ramamurthi and R.B. Ramaswami (see ibid., vol.IE-29, no.3, p.235-40 (1982)) is able to exhibit a higher performance when more stringent design considerations are adopted. The results show improvements in linearity and distortion as well as an extension in the frequency range with only small changes in circuit implementation
