Design of Low-Voltage Operational Amplifier (700mV)

Now-a-days there are many digital and analog circuits that are implemented by CMOS VLSI technology. Currently CMOS VLSI is progressing at fast rate and dominating most of the market. The low voltage VLSI circuits represent the electronic of the future. All electronics products are striving to reduce power consumption, to create more economical and efficient devices. For deep sub-micron CMOS technology the technique required to operate the circuit at low voltage is challenging. As power is directly related to the voltage in order to make a low power CMOS VLSI circuits we need to find an appropriate low voltage CMOS VLSI circuit. Here in this paper we have demonstrated a small signal low voltage operational amplifier operating at 700mV power supply.
