Abstract
In this paper, a pixelwise readout structure for a microbolometer is proposed. A current mirror gate modulation (CM) is employed as an input circuit to archive high responsivity and a current mode background suppression is used to reduce the integration capacitance. As a long integration time of more than 1 ms can be obtained using this pixelwise readout structure, the noise equivalent temperature difference (NETD) is 26 mK, which is much better than that of the conventional circuits, 67 mK.
