Table 2.
Scaling of ENOB with design characteristic/variable.
ADC characteristic | Example | ENOB scaling with characteristic | Remark | |
---|---|---|---|---|
1 | 2 | |||
τPSC | 8.98 bit|τPSC=32 ms | 9.99 bit|τPSC=64 ms | linear | |
Nneuron | 8.16 bit|Nneuron=32 | 9.65 bit|Nneuron=128 | ca. | |
Wres | 11.00 bit|Wres=5 bit | 10.92 bit|Wres=3 bit | no dependence | See hardware discussion, has to be above a lower bound |
fneuron,max | 7.69 bit|fneuron,max=50 Hz | 9.73 bit|fneuron,max=200 Hz | linear | Scaling saturates at approx. 0.5· Tsynch |
Tsynch | 6.81 bit|Tsynch=2 ms | 5.90 bit|Tsynch=4 ms | linear | Please note: For this sweep, fneuron,max = 50 Hz to avoid saturation |
Baseline characteristic as in Table 1, with resulting ENOB 10.98 bit.
