Linearized OTAs for high-frequency continuous-time filters: A comparative study Conference Paper uri icon

abstract

  • This paper presents a comparative study of three single-stage high frequency linearized OTAs for the design of high-performance continuous-time filters. The advantages and disadvantages of each structure are discussed. The two pseudo-differential OTAs are suitable for very low-voltage applications. One OTA is suitable for very high frequency applications and the other one has a very large linear signal swing and a large transconductance tuning range. The third OTA is based on complementary differential pairs and has very low power consumption. Design examples and experimental results are presented to demonstrate the performance characteristics of each structure.
