Claim 0:
1. A sensor controller comprising:
a sensor circuit comprising:
a light source driver to generate a driving signal;
a demultiplexer to produce, using the driving signal, a plurality of output driving signals, wherein each of the plurality of output driving signals is to be delivered to one of a plurality of sensors;
an amplifier coupled to each of the plurality of sensors, the amplifier to:
receive a first signal from a first sensor of the plurality of sensors, wherein the first signal is associated with a first event representative of a positioning of a substrate within a device manufacturing machine; and
generate, based on the received first signal, a second signal; and

an analog-to-digital converter to receive the second signal and generate, based on the second signal, a third signal; and

a logic circuit comprising:
a memory device storing instructions; and
a processing device coupled to the memory device, wherein the processing device is to obtain, using the stored instructions and based on the third signal, information about the positioning of the substrate within the device manufacturing machine.
