摘要： A high gain, low input capacitance clock buffer includes a plurality of transistors configured to supply an inverted representation of an input reference signal by alternatively switching to provide the output. While either of the transistors is operating to switch the input clock signal, the other transistor is in a stable state. Furthermore, by using n-type FET's, significant power reduction and space savings may be achieved.

摘要： A method for increasing the layer density uniformity across a conductive layer, which comprises a plurality of functional blocks, of an integrated circuit is presented. Increased uniformity is achieved by tiling a plurality of capacitors in between the functional blocks. The configuration of the capacitor array and number of the capacitor cells in the array is arranged so as to provide approximate uniformity in the conductor-to-non-conductor density across the entire conductive layer. The capacitor array may be used to reduce power supply switching noise by coupling one or more of the capacitor cells making up the capacitor array between a high power rail and a low power rail.

摘要： A master-slave flip-flop and method is provided for use with critical path circuits, for example, driving output pads on an integrated circuit. Briefly described, in architecture, the master-slave flip-flop comprises a master stage and a slave stage. The master stage includes a pass gate, an input inverter coupled to the pass gate, a feedback inverter coupled across the input inverter, and a driving inverter coupled to the output of the input inverter. The output of the driving inverter is coupled to the slave stage which includes a second pass gate through which the output of the driving inverter is applied to the master-slave flip-flop output. The above architecture results in a fast setup time and a fast clock-to-Q time without the problems associated with kickback. Also, the output of the master-slave flip-flop is tristatable.

摘要： The inventive mechanism provides a hysteresis margin to a comparator. The inventive mechanism generates two different voltage values, one high level and one low level, which forms the noise margin. The mechanism will select the proper level based on the output of the comparator. The comparator will then use the selected reference voltage, having either a slightly higher or lower level than a nominal reference value, as the reference voltage in its operations. The difference between each level and the nominal level is the added hysteresis noise margin. The inventive mechanism uses the higher voltage level when the output of the comparator is below the nominal reference voltage, and uses the lower voltage level when the output of the comparator is above the nominal reference voltage. Thus, a noise spike in the input signal would have to be larger than the margin provided by the mechanism, before causing the comparator to react to the noise in the signal. Since the mechanism is separate from the comparator, different comparators do not have be designed and tested. The mechanism can be disabled by a shorting some of the nodes of the mechanism together during the metal layer step of the device fabrication.

摘要翻译： 本发明的机构向比较器提供滞后余量。 本发明机构产生形成噪声容限的两个不同的电压值，一个高电平和一个低电平。 该机制将根据比较器的输出选择适当的电平。 然后比较器将使用所选择的参考电压作为其运行中的参考电压，具有比标称参考值略高或更低的电平。 每个电平和额定电平之间的差值是增加的滞后噪声容限。 当比较器的输出低于额定参考电压时，本发明的机构使用较高的电压电平，并且当比较器的输出高于标称参考电压时使用较低的电压电平。 因此，在使比较器对信号中的噪声作出反应之前，输入信号中的噪声尖峰将必须大于由该机构提供的余量。 由于该机制与比较器分离，因此不需要对不同的比较器进行设计和测试。 可以通过在器件制造的金属层步骤期间将机构的一些节点一起短路来禁用该机制。
