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.
