Update README.md
PLL-BASED CAPACITIVE SENSOR INTERFACE
This project involves the design of a capacitive sensor-to-digital converter using time-based circuit techniques. It uses basic digitally-oriented building blocks (two oscillators, a D-flipflop and a feedback loop including a capacitive element and a switch) to convert input capacitive values into digital single bit traces in the time domain. The basic block diagram can be seen below:
The architecture has been tested for a DC sweep of input capacitive values. The characteristic plot for an average window of 10us is seen below:
