A 1.5 V opamp design with high gain, wide bandwidth and its application in a high Q bandpass filter operating at 10.7 MHz

In this paper the design of a low voltage amplifier operating from 0 to 1.5 V single supply is presented first. The amplifier has the advantages of having a very high gain, a wide bandwidth, a fast settling time and a high output swing. The amplifier presented was designed in a 0.35 /spl mu/m CMOS technology. A proposed bandpass filter design operating at 10.7 MHz using the designed amplifier is analyzed. Simulation results of the proposed filter shows a good approach to design high Q bandpass filters.
