Active pixel sensor with bootstrap amplification and reduced leakage during readout

An integrated active pixel sensor array arranged in a plurality of rows and columns comprising:

• a plurality of row select lines, each of said row select lines associated with one row in the array and coupled to a source of a row-select signal;
• a plurality of source-follower drain row lines, each of said source-follower drain row lines associated with one row in said array and coupled to a source of a source-follower drain row signal;
• a plurality of column output lines, each of said column lines associated with one column in said array;
• a reset line coupled to a source of a reset signal;
• a transfer line coupled to a source of a transfer signal;
• a source of reset potential;
• and
• a plurality of active pixel sensors, each pixel sensor associated with one row and one column of the array and including a photodiode having a first terminal coupled to a first reference potential and a second terminal, a Reset transistor having a gate coupled to said reset line, a drain connected to said reset potential that reverse biases said photodiode, and a source coupled to said second terminal of said photodiode, a Transfer transistor having a gate coupled to said transfer line, a source coupled to said second terminal of said photodiode, and a drain, a Source-Follower transistor having a gate coupled to said source of said Transfer transistor, a drain coupled to the one of said plurality of source-follower drain row lines with which its active pixel sensor is associated, and a source, a Row-select transistor having a gate coupled to the one of said plurality of row-select lines with which its active pixel sensor is associated, a drain coupled to said source of said Source-follower transistor, and a source coupled to the one of said plurality of column output lines with which its active pixel sensor is associated.
