TEMPERATURE COMPENSATION CIRCUIT AND RADAR APPARATUS |
摘要 |
A temperature compensation circuit includes: an oscillation circuit configured to include a replica amplifier of a target amplifier to be subjected to temperature compensation and oscillate by feeding an output of the replica amplifier back to an input; a time measurement circuit configured to measure a measured rise time taken from a start of oscillation of the oscillation circuit until an amplitude of an oscillation signal reaches a specific amplitude in the oscillation circuit; and a control circuit configured to compare a reference rise time of the oscillation circuit measured under a reference condition and the measured rise time and change a driving condition of the replica amplifier such that the measured rise time becomes substantially equal to the reference rise time. |

1. A temperature compensation circuit comprising:
an oscillation circuit configured to include a replica amplifier of a target amplifier to be subjected to temperature compensation and oscillate by feeding an output of the replica amplifier back to an input; a time measurement circuit configured to measure a measured rise time taken from a start of oscillation of the oscillation circuit until an amplitude of an oscillation signal reaches a specific amplitude in the oscillation circuit; and a control circuit configured to compare a reference rise time of the oscillation circuit measured under a reference condition and the measured rise time and change a driving condition of the replica amplifier such that the measured rise time becomes substantially equal to the reference rise time. |
