-Be sure to start up the digital pulse source output on the Analog Discovery Lab board before turning on the +5V bench supply. The boosted output voltage at node V<sub>OUT</sub> should be observed and should be approximately equal to 2 times the DC value of the bench supply.+Be sure to start up the digital pulse source output on the ADALM2000 Lab board before turning on the +5V bench supply.

-What sort of circuit could you make to generate the 100 KHz square wave other than using the digital pulse source output on the Analog Discovery Lab board? There are four additional inverters in the 74HC04 package. The other inverters along with RC delay network, R<sub>4</sub> C<sub>4</sub> can be configured into a ring oscillator as shown below. The values for R<sub>4</sub> and C<sub>4</sub> are approximate for 100 KHz and can be adjusted as needed.+What sort of circuit could you make to generate the 100 KHz square wave other than using the digital pulse source output on the ADALM2000 Lab board?
