Abstract:
1. An electronic circuit comprising: a first power supply line; a second power supply line configured to be located along the first power supply line; a plurality of first circuits each including a first FET and configured to be located along the first power supply line and the second power supply line, each of the plurality of first circuits connected to a first power supply node through the first power supply line, and connected to a second power supply node through the second power supply line, a first power supply voltage applied to the first power supply node being changed into changed first power supply voltages based on a distance from the first power supply node to each of the plurality of first circuits, a second power supply voltage applied to the second power supply node being changed into changed second power supply voltages based on a distance from the second power supply node to each of the plurality of first circuits, each of the plurality of first circuits being supplied with a respective one of the changed first power supply voltages and a respective one of the changed second power supply voltages, the first FET of each of the plurality of first circuits having a source supplied with at least one of the respective one of the changed first voltages and the respective one of the changed second power supply voltages; and a plurality of second circuits each being associated with a respective one of the first circuits, located along the first power supply line and the second power supply line, and each configured to generate a back bias voltage applied to the first FET of the respective one of the first circuits, so that the back bias voltage changes in accordance with at least one of the respective one of the changed first power supply voltages and the respective one of the second power supply voltages.
