    • A current source providing an output current with a fixed current range includes a bias circuit, a resistor, a current mirror, and a controller. The bias circuit provides a first voltage weighted with a first tunable coefficient and a second voltage weighted with a second tunable coefficient. The resistor has a tunable resistance for determining a bias current according to a voltage difference between the first and the second voltages and the tunable resistance. The current mirror generates the output current according to the bias current. The controller adjusts the tunable resistance and one of the first and the second tunable coefficients to achieve a voltage-current coefficient with different values, while the bias current and the output current are kept within a fixed current range.
    • 提供具有固定电流范围的输出电流的电流源包括偏置电路,电阻器,电流镜和控制器。 偏置电路提供用第一可调系数和第二可调系数加权的第二电压加权的第一电压。 电阻器具有根据第一和第二电压之间的电压差以及可调谐电阻来确定偏置电流的可调电阻。 电流镜根据偏置电流产生输出电流。 控制器调节可调谐电阻和第一和第二可调谐系数之一,以实现具有不同值的电压 - 电流系数,而偏置电流和输出电流保持在固定电流范围内。
