20150309527 | TEMPERATURE COEFFICIENT FACTOR CIRCUIT, SEMICONDUCTOR DEVICE, AND RADAR DEVICE - A temperature coefficient factor circuit is provided which generates a current which varies with temperature according to a programmable temperature coefficient factor. The temperature coefficient factor circuit comprises a first current source providing a first current with a positive temperature coefficient factor, a second current source providing a second current with a negative temperature coefficient factor, a common terminal, a first programmable amplifying current mirror, a second programmable amplifying current mirror and a current output circuit. The first programmable amplifying current mirror provides in dependence of a control signal ctrl an amplified first current to the common terminal. The second programmable amplifying current mirror conducts away in dependence of the control signal ctrl an amplified second current from the common terminal. The current output circuit provides the output current based on a difference current between the amplified first current and the amplified second current. | 10-29-2015 |
