Summary: In this letter, two kinds of MOS operational transconductance amplifiers (OTAs) based on combiners are presented. Each OTA has the following advantages; one of the proposed OTAs (OTA-1) can be operated at low supply voltage and the other OTA (OTA-2) has wide bandwidth. Through HSPICE simulations with a standard 0.35 µm CMOS device parameters, the operation under the supply voltage of 1.5 V for OTA-1 and the -3 dB bandwidth of several gigahertz for OTA-2 are confirmed. | ||||||||||
