| - | ==== Meeting Minutes March 14, 2021 ==== | ||
| - | **Attended: Lauryn, Francis, Brian, Thiri, Yin** | ||
| - | === Updates === | ||
| - | * Traced & debug v4.1 | ||
| - | * Used the wrong capacitors - C4, C9, C10, C11 (used 10uF instead of 0.1uF) | ||
| - | * Got help from professor Weldon (looked at Volt. reg. schematic) | ||
| - | * Identified that feedback is not connected to Vout | ||
| - | * Cannot verify that capacitor 5 (C5) is connected to Vout (Schematic does not show that) | ||
| - | * Adding the Jumper wire causes issues with C2 and C5 | ||
| - | * Suggested by manufacturer you need a 1.0uF, 10uF and 8.2pF that is separated to have a different output freq. | ||
| - | * instead we have C1 = 1.0uF, C15 = 18pF on our board | ||
| - | * As reference: | ||
| - | {{ :weatherbox:bumblebee:image.png?600 |}} | ||
| - | ===To Do=== | ||
| - | * Solder the correct Capacitors | ||
| - | * Download Pspice | ||
| - | * Stimulate voltage reg. and download library/parts | ||
| - | * stimulate ideal situation | ||
| - | * stimulate non-ideal situation to get close to 5V | ||
| - | * Min value: 1/2x cap. value | ||
| - | * Max Value: 2x Cap. value | ||
| - | * Create new schematic for new version | ||
