This is the simulation of a Ultrasound Receiver using the 741 IC, an operational amplifier. Equivalent can be tested. The circuit can operate in frequencies up to 50 kHz but other operationals can go beyond this limit. The gain is given by R1. This component can be changed. The signal sources is adjusted to source a 100 mV x 30 kHz. Se more in the simulation. Figure 1 shows the circuit used in the simulation.
