  1. HKN ECE 342 Review Session 1 Anthony Li Keshav Harisrikanth

  2. KVL/KCL • Sum of all voltages in a loop is 0 • Sum of current entering a node equals sum of current exiting a node

  3. Incremental/Small Signal Model • Can be numerically derived from Taylor Series approximation (up to first-order term) • Taylor Series:

  4. MOSFET’s • NMOS • PMOS

  5. MOSFET Operating Point • Three regions of operation: • Cutoff (VGS < VT): ID = 0 • Linear/Triode (VGS > VT, VDS < VGS - VT): • Saturation (VGS > VT, VDS > VGS - VT): • Note:

  6. MOSFET Incremental Model Transconductance:

  7. Current Mirrors • Transistors sharing the same “mirror” current – just a ratio of transistor sizing.
