Design of High Voltage Integrated Class-F Amplifier for Ultra Sound Transducers
Journal Title: International Journal for Research in Applied Science and Engineering Technology (IJRASET) - Year 2015, Vol 3, Issue 10
Abstract
Pulsers are usually adopted in ultra sound applications due to their efficiency. On the other hand, amplifiers would enable apodization profiles with high resolution; beams with low harmonic content and instantaneous changes in transmit energy between pulses. Their use is rather limited when relying on a discrete technology approach, due to high manufacturing costs and space occupation. In view of an increased level of integration, the availability of a BCD technology, capable of watts level driving at high frequency, encourages investigation of linear amplifiers, the topic of this work. Advantages in terms of reliability, space and cost would derive. The proposed amplifier, closed in a feedback loop, uses a high low-voltage transconductor driving a high voltage trans-impedance stage operating in class-B. Device parameters vary with signal amplitude making circuit analysis involved. Techniques to analyze large signal frequency response, distortion and stability are proposed in this paper leading to useful design insights.
