Abstract
A time domain temperature sensor circuit includes a voltage generating circuit configured to generate and equalize a first voltage of a first node and a second voltage of a second node, a current generating circuit comprising a first semiconductor device connected between the first node and a ground, and configured to generate a first current, and a variable resistor circuit and a second semiconductor device connected in series between the second node and the ground, and configured to generate a second current, the variable resistor circuit being configured to vary a temperature gradient of the second current based on resistance variations by the variable resistor circuit, and a current mirror circuit configured to generate a third current by performing current mirroring of the second current and transmit the third current to an output terminal.
