@Muse - Here is the exact electrical and topological dual ("opposite") of the attached circuit:
- **Active Device Dual:** The NPN transistor has been inverted to a PNP transistor #Q1.
- **Reactive Component Swap:** Every capacitor ($1\ \mu\text{F}$) has been replaced by an inductor ($1\ \text{nH}$), and every series inductor ($1\ \text{nH}$) has been replaced by a capacitor ($1\ \mu\text{F}$).
- **Orientation & Polarity:** The ground reference and branch orientations are inverted vertically to complement the PNP active-device polarity while preserving the underlying five-stage ladder topology and waveform probing.
