What is A balanced output CMOS OTA with wide linear current tunable range about?
A new CMOS-based balanced output operational transconductance amplifier (BOTA) with very wide linear current tunable range is proposed in this paper. The design technique is achieved by the combination of a fully differential transconductor and an electronically variable current gain stage. The transconductance gain of the proposed BOTA can be linearly tuned by an external bias current for more than 4 decades, with less than 4% nonlinearity for the linear input-voltage range of about 0.2 V peak . The OTA is designed in 0.5 m AMIS technology. The performance of the proposed circuit is discussed and confirmed through application example and PSPICE simulation results.
