In this episode, we'll design a super simple JFET-based DIY sample & hold-circuit. Because I've only ever used BJTs before, the video also doubles as a deep dive into JFET basics. If you want to follow along (which I strongly recommend), here's a bill of materials:

1x TL074 quad op-amp
1x J113 (or J112/J111) n-channel JFET
2x 1N4148 diode
1x 100k linear mono potentiometer
1x 1M resistor
3x 100k resistor
1x 33k resistor
1x 1k resistor
1x 100 nF film capacitor
1x 1nF film capacitor
