MIT FabAcademy Week6 Note- Electronics Design

Component

• wire: ribbon cable

• switch: button

• resistor(电阻): I=V/R
  

• capacitor(电容): C = Q/V, I = C dV/dt

  • unpolarized 无极，voltage can go either direction
    
  • polarized 有极，voltage can only go one direction
    

• crystal(tell time), resonator(晶体谐振器)

  
  

• inductor(电感): V = L dI/dt, used as filters that prevent signals changing quickly.

  

• diode(二极管): current from anode(正极) to cathode(负极)
  PN,Schottky,Zener,(what's the difference?)
  LED

• transistor(晶体管)

  • bipolar(双极的, always use current): collector(集电极), emitter(发射器), base current gain()
  • mosfet(金属氧化物半导体场效应晶体管): source, drain, gate resistance
    

• regulator(调节器)

• op-amp(运算放大器)

  

• microcontroller(微控制器)

  

  AVR

• sensors(传感器)

• actuators(驱动器)

Circuits

Kirchoff's laws: sum current at node, voltage around loop = 0

power: P = I^2 R = I V

Steps: schematic entry(电路图输入), component placement, (auto)routing, simulation, fabrication
