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 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:
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
