    • PURPOSE: A active pixel sensor with reset noise suppression and programmable binning capability is provided to reduce noise generated by injected ions by homogenizing injected ions among adjacent pixels. CONSTITUTION: An imaging circuit includes a P- type epitaxial silicon substrate(16), a plurality of N- well pixel cells(12) and binning connections(22). The N- well pixel cells are formed in the P- type epitaxial substrate and are surrounded by the P- type epitaxial silicon. The binning connections between selected adjacent N- well pixel cells can be used to selectively bin adjacent N- well pixel cells. The binning connections include an N+ silicon between the selected adjacent N- well pixel cells. The N+ silicon between selected adjacent N- well pixel cells is used to form an NMOS transistor between those selected adjacent N- well pixel cells and forms an optional binning switch.

    • PURPOSE: To always minimize noise component even if production variation occurs in transistor characteristics, resistance value and the like. CONSTITUTION: K pieces of clock phase difference generation circuits 16-18 shift the phase of basic clock signal ADCK1 by different predetermined values and supply them to an A/D converter as a clock signal ADCK2. K pieces of counters 19 sequentially select each of the clock phase difference generation circuits 16-18 and stores the noise component of A/D converter output which is determined by noise measurement circuit 27 in corresponding resistors at each selection. A comparator circuit 25 compares k noise components to find the number j for the smallest value. Selection circuit 26 fixedly selects only jth clock phase difference generation circuit. Thus, even if a variation occurs in the transistor characteristics or the resistance value in individual device, the clock signal ADCK2 which shifted the phase of the basic clock signal ADCK1 can be supplied to the A/D converter to minimize the noise component.
    • 目的:即使在晶体管特性,电阻值等方面出现生产变化,也要始终尽量减少噪声分量。 构成:K个时钟相位差发生电路16-18将基本时钟信号ADCK1的相位移动不同的预定值,并将它们作为时钟信号ADCK2提供给A / D转换器。 K个计数器19依次选择时钟相位差发生电路16-18,并将由噪声测量电路27确定的A / D转换器输出的噪声分量存储在每个选择的相应电阻中。 比较器电路25比较k个噪声分量以找到最小值的数字j。 选择电路26仅固定地选择第j个时钟相位差产生电路。 因此,即使在单个器件中的晶体管特性或电阻值中发生变化,可以将基本时钟信号ADCK1的相位偏移的时钟信号ADCK2提供给A / D转换器,以使噪声分量最小化。
