Traditionally BJT or BiCMOS amplifiers have been used to achieve equivalent input noise densities of 1 nV√Hz or less, as desirable in some ultrasonic applications. Due to an increasing demand on increased integration it can be necessary to implement the amplifier in a CMOS process. As part of this design process we applied the particle swarm optimization to the problem of optimizing an amplifier specifically for operation in the 2-4 MHz frequency band. We present measurements on the manufactured circuit with performance comparable to the best available BJT-based amplifiers available today.
