The development of manufacturers and designers is looking the methods for conventional smaller-sized and high-performance devices with the circuit reduced the power consumption and enhanced the gain margin, phase margin is the most important parameter of an operational transconductance amplifier (OTAs). Which have become essential building blocks of many modern analogy and mixed–the signal circuit is used as a key element in a wide variety of circuits that benefit from voltage control. In essence, an OTA is a direct-coupled differential voltage-controlled current source (DVCCS) with high output impedance. Which is a low voltage (LV) and low power (LP) in this project the structures for different methodologies and compares in terms of gain and bandwidth, phase, unity gain bandwidth (UGB) and speed, size most of the analog system needs an LV and LP power supply.
