Pixel circuit arrays
First Claim
1. A pixel circuit array, comprising:
- a plurality of pixel circuits; and
a global reset transistor that has a first end connected to a second end of a reset transistor of each of the pixel circuits and is turned on or off in response to a global reset signal;
wherein each of the pixel circuits comprises;
a transmission transistor that receives photocharges from a photodiode through a first end of the transmission transistor and transmits the received photocharges through a second end of the transmission transistor in response to a transmission control signal;
the reset transistor that has a first end connected to the second end of the transmission transistor and is turned on or off in response to a reset control signal;
a source-follower transistor that receives a signal output from the second end of the reset transistor through a gate of the source-follower transistor and is turned on or off in response to the received signal; and
a selection transistor that is connected to the source-follower transistor and is turned on or off in response to a selection control signal.

Abstract
A pixel circuit array may include pixel circuits and/or a global reset transistor that has a first end connected to a second end of a reset transistor and is turned on or off in response a global reset signal. Each pixel circuit may include: a transmission transistor that may receive and/or transmit photocharges through ends of the transmission transistor in response to a transmission control signal; the reset transistor that may have a first end connected to the second end of the transmission transistor and may be turned on or off in response a reset control signal; a source-follower transistor that may receive a signal from the second end of the reset transistor and/or may be turned on or off in response the received signal; and/or a selection transistor that may be connected to the source-follower transistor and/or may be turned on or off in response a selection control signal.
