Blocks

This is the durable/instance split in action. Each block has a durable page (theory + procedure) and per-chip instance pages.
| Block | Durable page | RC1.9 | RC2.0 |
|---|---|---|---|
| Switched-cap LPF | SC LPF | RC1.9 | RC2.0 (TBD) |
| AFE (Gm-C integrator) | AFE Gm-C | RC1.9 | RC2.0 (TBD) |
| SAR ADC | SAR ADC | RC1.9 (TBD) | RC2.0 (TBD) |
| Stimulator | Stimulator | RC1.9 (TBD) | RC2.0 (TBD) |
| Bias / bandgap | Bias Bandgap | RC1.9 (TBD) | RC2.0 (TBD) |
| EDO attenuator | EDO Attenuator | RC1.9 (TBD) | RC2.0 (TBD) |
Recurring blocks: AC-coupled low-noise front-end (Gm-C integrator + switched-cap LPF), SAR ADC, current-steering stimulator with charge balancing, constant-gm and bandgap biasing, pseudoresistor high-pass networks, switched-cap charge-sharing EDO attenuator.
Default core analog supply is 0.9 V for the 28nm parts unless a page says otherwise.
