Bobbywhy said:If you give more specific details you are more likely to get more useful suggestions. Describe your project and its objectives or purpose.
1. What kind of signal from your signal generator are you trying to amplify?
2. Does the signal generator have an "output level" adjust?
3. What will be your "load"...that is, what are you trying to drive with this amplified signal?
4. How much voltage or power is needed?
There are manufacturer "application notes" for practically any kind of amplifier you may need and tons of information free on the internet. Once you give your plan members here can guide you to books and other sources.
Bobbywhy said:Often signal generators have a control that enables you to control the output voltage level. I am only asking if your generator does have such a control.
So your signal generator gives 10V output. How do you know that? Did you measure it with an O'scope? An AC voltmeter? Is it 10V peak-to-peak or 10V rms?
Your amplifier will need a power supply with slightly greater than 100 Volts. By convention, this is considered "High Voltage" so caution for your own safety is MANDANTORY. The capacity of this power supply needs to be enough to drive your load. It takes energy (that means power here) to drive the piezo disc.
I recommend a high voltage FET amplifier for your project. It is fairly cheap, reliable, and simple to build.
Will you apply the 1.7MHz to the piezoelectric disc continuously? If yes, it may overheat.
Mike_In_Plano said:Hmmm, 1.7MHz at 100V into what's probably a heavily capacitive load. This does sound difficult for your typical linear amplifier.
Ultrasonic baths typically use power oscillators for this. My personal favorite is the Royer oscillator, and I've taken it up to this level using mosfets. If you wish to do so, I can give you some suggestions, offline, but you'll need to make yourself a transformer and likely an inductor. Otherwise, it's fairly simple and can be built on perf board and powered from 12 volts.
You'd also need access to an oscilloscope to ensure it's doing what you want.
To build an amplification circuit, you will need a power supply, resistors, capacitors, transistors, and an audio input and output device. You may also need a breadboard, jumper wires, and a soldering iron if you are building a permanent circuit.
The key components to consider when choosing parts for your amplification circuit are the type and value of the resistors, the capacitance and voltage rating of the capacitors, and the gain and frequency response of the transistors. You should also consider the power requirements of your circuit and ensure that the components can handle the necessary voltage and current.
No, it is important to choose the right type of transistor for your circuit. Bipolar junction transistors (BJTs) are commonly used for audio amplification, while field-effect transistors (FETs) are better suited for high-frequency applications. You should also consider the gain and voltage ratings of the transistor when selecting one for your circuit.
While you can certainly follow a specific circuit diagram, you can also design your own circuit as long as you understand the principles of amplification and the components involved. It is important to follow best practices for circuit design and include the necessary components for proper amplification and signal filtering.
To test your amplification circuit, you can use a multimeter to measure the voltage and current at different points in the circuit. You can also use an oscilloscope to visualize the input and output signals. If your circuit is not functioning properly, you can troubleshoot by checking for loose connections, incorrect component values, or damaged components. It may also be helpful to consult online resources or seek advice from experienced circuit builders.
