A CMOS digitally programmable class AB OTA circuit
2000 (English)In: IEEE transactions on circuits and systems. 2, Analog and digital signal processing (Print), ISSN 1057-7130, E-ISSN 1558-125X, Vol. 47, no 12, 1551-1556 p.Article in journal (Refereed) Published
Abstract [en]

A new low-voltage CMOS digitally programmable operational transconductance amplifier (OTA) circuit is presented, The circuit utilizes simple class AB voltage buffers to provide a non slew rate limited performance with low standby power consumption. The OTA can be digitally programmed to maintain a constant settling time for different load capacitors without increasing the stand by power consumption. Experimental results from a 1.2-mum chip and comparisons with the regular folded cascode OTA circuit are given. The proposed circuit power consumption is found to be less than one third of a regular folded cascode OTA when driving a load capacitance of 35 pF, For the same power consumption level of 240 muA, the new circuit achieves a slew rate more than 10 V/mus while the traditional folded cascode fails to settle.
