Transconductance enhancement method for operational transconductance amplifiers

Electronics Letters, 2010
An improved recycling structure for an operational transconductance amplifier is proposed. The proposed structure separates the AC path from the DC path, and achieves a significant boost in transconductance under the same power and area budget. A folded-cascode amplifier employing the improved recycling structure was implemented in SMIC standard 0.13 ...
