Claim 18:
19. The temperature sensing circuit of claim 18, wherein the switched capacitor circuit further comprises:
a thirteenth switch having a first node coupled to ground, wherein the thirteenth switch operates in response to the third control signal;
a fourteenth switch having a first node coupled to a second node of the thirteenth switch and a second node coupled to a first node of the first fixed capacitance, wherein the fourteenth switch operates in response to the first control signal;
a fifteenth switch having a first node coupled to a second node of the first fixed capacitance and a second node coupled to the non-inverting input of the integrator, wherein the fifteenth switch operates in response to the second control signal;
a sixteenth switch having a first node coupled to the second node of the thirteenth switch and a second node coupled to the common mode voltage, wherein the sixteenth switch operates in response to the fourth control signal;
a seventeenth switch having a first node coupled to the first node of the first fixed capacitance and a second node coupled to the common mode voltage, wherein the seventeenth switch operates in response to the second control signal; and
an eighteenth switch having a first node coupled to the second node of the first fixed capacitance and a second node coupled to the common mode voltage, wherein the eighteenth switch operates in response to the first control signal.
