摘要： A ferroelectric/pyroelectric sensor employs a technique for determining a charge output of a ferroelectric scene element (134) of the sensor by measuring the hysteresis loop output of the scene element (134) several times during a particular time frame for the same temperature. An external AC signal is applied to the ferroelectric scene element (134) to cause the hysteresis loop output from the element (134) to switch polarization. Charge integration circuitry (138), such as a combination output capacitor and operational amplifier, is employed to measure the charge from the scene element (134). Preferably, the ferroelectric of the scene element (134) is made of SBT or derivative thereof, disposed directly between the top and bottom electrodes. Because of the frequency characteristics of the sensor, created by the external AC signal, the element (134) need not be thermally isolated from the silicon substrate by a traditional air bridge, and instead is preferably thermally isolated by spin-on-glass, SOG. To prevent saturation of an output signal voltage of the sensor by excessive charge accumulation in an output capacitor, the sensor has a reference element (132) in parallel with the scene element (134). When the voltage of the AC signal is negative the output capacitor is discharged by flowing current through the reference element (132) thus interrogating the polarization of the reference element (132) which is compared to and subtracted from the polarization of the scene element (134) for each cycle. The polarization difference measured for each cycle over a set time period are summed by an integrating amplifier to produce a signal output.

An external AC signal is applied to the ferroelectric scene element to cause the hysteresis loop output from the element to switch polarization. Charge integration circuitry, such as a combination output capacitor and operational amplifier, is employed to measure the charge from the scene element. Preferably, the ferroelectric of the scene element is made of an economical and responsive strontium bismuth tantalate, SBT, or derivative thereof, disposed directly between top and bottom electrodes. Because of the frequency characteristics of the sensor, created by the external AC signal, the element need not be thermally isolated from the silicon substrate by a traditional air bridge, which is difficult to manufacture, and instead is preferably thermally isolated by spin-on-glass, SOG. To prevent saturation of an output signal voltage of the sensor by excessive charge accumulation in an output capacitor, the sensor preferably has a reference element configured electrically in parallel with the scene element. When the voltage of the AC signal is negative the output capacitor is discharged by flowing current through the reference element thus interrogating the polarization of the reference element which is compared to and subtracted from the polarization of the scene element for each cycle. The polarization difference measured for each cycle over a set time period are summed by an integrating amplifier to produce a signal output voltage.
