Synopsis

Keywords: New Devices, New DevicesAn in-bore PIN diode driver with eight output channels is presented here. The driver is based on a single-chip solution making the implementation simple and of high performance. The rise and fall times of the driver's output are in the single-digit nanosecond range with a peak output current of up to 5.7A per channel. Triggering the driver can be done either with an optical or electrical signal. The driver was tested on the bench and in-bore of a 10.5T MR scanner.
