		The 4069 VCO was designed by Ren&eacute; Schmitz, schematics can be found on
		<a href="http://www.uni-bonn.de/~uzs159/vco4069.html">his site</a>.<br/>
		<br/>
		I really like the 4069 VCO of several reason:
		<img alt="" class="right" src="schematics/4069vco_boost.gif"/>
		<ul>
			<li>It's simple to understand, thus debug</li>
			<li>It's cheap</li>
			<li>It's stable enough</li>
		</ul>
		My version of the 4069 vco contains a slightly modified boost stage for the saw output
		as shown to the right, i have this here because it's incorporated in the breadboard layout
		of the 4069 vco found below.<br/>
