Abstract
Methods and apparatus are disclosed for broadening the bandwidth of a radiation detector and diminishing heat generated noise generated within the detector in order to enhance detectivity. The improved performance is achieved by applying a pulsed bias to the detector which consists of a sequence of waveforms which reduces the duty cycle of the detector in comparison to a detector subjected to a constant bias. A sophistication of this use of a pulsed bias is the utilization of a swept bias which employs a sequence of waveforms having gradual rise-times which further reduces unwanted detector noise and enhances detectivity.
