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.
          • BufDiffPair
