文摘
- •
We propose a new light to frequency converter to detect wide luminance range.
- •
We extract the math behind the circuit operation.
- •
The sensitivity of the circuit is higher than typical circuits in the worst case.
- •
The nonlinear characteristic of the circuit is essential to capture a clear image.
- •
There is not any distortion in the conversion because of voltage variation.
