Comment on 2-MOSFET transresistor with extremely low distortion for output reaching supply voltages (and reply)

For original paper see Z. Wang et al., ibid., vol.26, p.951-2 (1990). The commenters make two points; the 2-MOSFET transresistor has been published already three years ago; the maximum available range for the output should be written differently. In reply, the original author states that the work was carried out independently two years ago. Both inspiration for the work and additional differences within it are also discussed.
