Abstract: A ferroelectric reference circuit generates a reference voltage proportional to (P+U)/2 and is automatically centered between the bit line voltages corresponding to the P term and the U term across wide temperature and voltage ranges. To avoid fatiguing the reference ferroelectric capacitors generating (P+U)/2, the reference voltage is refreshed once every millisecond. To eliminate the variation of the reference voltage due to the leakage in the ferroelectric capacitors during this period of time, the reference voltage generated from the reference ferroelectric capacitors is digitized when it is refreshed. The digital value is fixed and converted to an analog value which is then fed into sense amplifiers for resolving the data states. The reference voltage is automatically at the center of the switching (P) and non-switching (U) signals and therefore the signal margin is maximized.

Abstract translation: 铁电参考电路产生与（P + U）/ 2成比例的参考电压，并且在宽温度和电压范围内自动居中对应于P项和U项的位线电压。 为了避免产生（P + U）/ 2的参考铁电电容器疲劳，参考电压每毫秒刷新一次。 为了消除在这段时间内由于铁电电容器的泄漏引起的参考电压的变化，当刷新时，从参考铁电电容器产生的参考电压被数字化。 数字值被固定并转换为模拟值，然后将其馈送到读出放大器中以解析数据状态。 参考电压自动处于开关（P）和非开关（U）信号的中心，因此信号余量最大化。

Abstract: Consistent with an aspect of the present invention, a lateral bipolar transistor is provided that exhibits similar performance as that of high speed vertical bipolar junction transistors. The lateral bipolar transistor includes a polysilicon side-wall-spacer (PSWS) that forms a contact with the base of the transistor, and thus avoids the process step of aligning a contact mask to a relatively thin base region. The side wall spacer allows self-alignment of the base/emitter region, and has reduced base resistance and junction capacitance. Accordingly, improved cutoff frequency (fτ) and maximum oscillation frequency (fmax) can be achieved. Moreover, this novel topology enables the realization of Bipolar CMOS (BiCMOS) technology on insulating substrates, such as SOI.

Abstract translation: 根据本发明的一个方面，提供了一种横向双极晶体管，其表现出与高速垂直双极结型晶体管相似的性能。 横向双极晶体管包括与晶体管的基极形成接触的多晶硅侧壁间隔物（PSWS），从而避免了将接触掩模对准相对薄的基极区域的工艺步骤。 侧壁间隔物允许基极/发射极区域的自对准，并且具有降低的基极电阻和结电容。 因此，可以实现改进的截止频率（ftau）和最大振荡频率（fmax）。 此外，这种新颖的拓扑结构使得能够在诸如SOI的绝缘衬底上实现双极CMOS（BiCMOS）技术。
