...photocircuit

I have adopted the term ``photocircuit'' because of its clear and sharp reference to a circuitry which processes the photocurrent or photovoltage. Other terms, such as ``photoreceptor'', have been interchangeably used both for single photodetectors and the circuitry used for processing photocurrents, and in a context full of these references become confusing.

...resistance

In recent processes the gate poly is silicided which significantly reduces the sheet resistance. For example, a silicided poly has a sheet resistance of 2 OHMs/Square, while for an amorphous silicon gate this is about 20-50 OHMs/Square.

...circuits

Dynamic current mirrors are an example of sampled data storage element. However, the principal function of these circuits is to store the gate voltage. Therefore, the storage is essentially working in voltage mode.
