Claim 6:
7. The temperature sensing circuit of claim 6, wherein the switched capacitor circuit further comprises:
a nineteenth switch having a first node coupled to the base-emitter voltage of the third bipolar junction transistor, wherein the nineteenth switch operates in response to the fourth control signal;
a twentieth switch having a first node coupled to a second node of the nineteenth switch and a second node coupled to a first node of the fourth capacitor, wherein the twentieth switch operates in response to the first control signal;
a twenty first switch having a first node coupled to a second node of the fourth capacitor and a second node coupled to the inverting input of the integrator, wherein the twenty first switch operates in response to the second control signal;
a twenty second switch having a first node coupled to the second node of the nineteenth switch and a second node coupled to the common mode voltage, wherein the twenty second switch operates in response to the third control signal;
a twenty third switch having a first node coupled to the first node of the second capacitor and a second node coupled to the common mode voltage, wherein the twenty third switch operates in response to the second control signal; and
a twenty fourth switch having a first node coupled to the second node of the second capacitor and a second node coupled to the common mode voltage, wherein the twenty fourth switch operates in response to the first control signal.
