A Fully Balanced Two-input, High-frequency, Widely Linear-tunable OTA and its Application to Filters
Cheng Jian · Journal of Circuits and Systems · 2004
A fully balanced two-input, high-frequency widely linear-tunable OTA is proposed for the application in wide range of linear-tunable high-frequency continuous-time filters. It is proved by simulation that with phase compensation, the proposed OTA has not only ideal linear input characteristics and tunable frequency range, but also better frequency response in HF applications such as filters.
