bGoblin is born! We received the module from the fab today. This small module is composed of:
- A time-gain-control (or a VGA) to compensate for the ultrasound attenuation
- An enveloppe detector, to actually get the echoes
- An amp to better stretch the signal before it goes to the...
- 3Msps ADC
How does it work?
Which, in functional blocks, gives:
It works! Let's try it with a 3MHz burst:
Or, if we buff up the signal: with the gain control, to make it better "readable" with the ADC:
