I have a challenge. Design a Femto Coulomb Amplifier and win a prize. I have 1us pulsed signal of 0.1fC charge with 10ns rise time and decay time and want to amplify it above noise with S/N > 10. The capacitance of the detector source is 100pF, which hold this charge from an Ion Beam Source. I want to amplify it to 10mV/fC. Output rise time and decay time of 50ns is acceptable. Use any real components that are discretely available on the market. Test the design and let me know how it works. Do not use an imaginary design or non-existant components. The best working design will be entitled to a prize of US$1000. If a design is accepted and agreed then the real circuit can be sent to us for final testing. I hope this will help some great engineers to try our their skill.
I'll be happy to discuss design ideas but you will not be eligible for prize. This design is on the cutting edge and requires real engineering work.
I will monitor the developments for 90 days.
