This is a library for circuits for a multi-phase clock generation and rotation circuit based on multi-phase injection-locked ring oscillators.

Circuit Hierarchy (outline)

TopV1: AMS core block
- CoreOutDAC - Core oscillator + C2C output buffers + IDACs
  - Core - Oscillator core
    - CoreUnit - Oscillator core unit cell
      - CoreDiffPair - diff pair array
      - DiffRes (bag3_analog)
  - CML2CMOS_diff_AC - Psuedodiff CML2CMOS - AC-coupled TIA
    - CML2CMOS_AC - Single-ended CML2CMOS
      - mosres - Stacked MOS resistor, for TIA feedback
      - inv (bag3_digital)
      - mos_cap
  - IDACArray - IDAC, with on / off switches
    - IDACUnit
      - IDACCell
- InBuff - Input replica buffer + replica bias
  - InBuffCore - Input replica core
    - HighPassFilter (bag3_analog) - AC coupling the input
    - BufCore - replica swing conditioning
      - BufUnit - buffer unit cell. Generator can instantiate multiple.
