 ## How it works
 
-Explain how your project works
+It is a simple voltage-controlled oscillator, based on ring oscillator with transmission gate <br/>
+to control current flow to the gates. <br/>
+The inverter gates are wired in parallel with a capacitor, to ensure that it remains linear when charging <br/>
+This should directly affect the gate voltage when charging. ensuring that it stays in linear region means that <br/>
+changes in resistance will proportionally change the charging time of the capacitor (e.g. 2x increase in <br/>
+resistance will result in 2x longer charging time, thus halving the frequency of the oscillator), although this <br/>
+concept will be limited by the linearity of the mosfets in the transmission gates. 
+<br/>
+<br/>
+it is currently unknown why this works, since the the concept is very similar to a mosfet with really big <br/>
+gate capacitance. Might be something with the current draw when charging, using cap vs not using cap?
 
 ## How to test
 
-Explain how to use your project
+To test the oscillator, 2 power supply as the oscillator input is required <br/>
+the VCON+ and VCON- can be thought as a differential input. to get maximum frequency, <br/>
+connect 1.8V to VCON+ and 0V to VCON-. The frequency should be between 6-7 MHz.
