    Abstract: The invention relates to an amplifying circuit and to a method for correcting the pulse duty factor of a differential clock signal (CLt, CLc) to give a desired value of 50 % using a differential amplifier (1) having an MOS transistor pair (T1, T2). According to said method, the clock signal (CLt, CLc) to be corrected is applied to the respective gate of the MOS transistor pair (T1, T2), and a differential analog pulse duty correction signal (DCt, DCc) is produced by respective integration of the true and complementary clock signal (ACLt, ACLc) emitted by every MOS transistor (T1, T2) of the differential amplifier (1) on its source/drain connection. The differential pulse duty correction signal (DCt, DCc) thereby obtained is applied to the respective electrically insulated substrate connections (S1, S2) of the MOS transistor pair (T1, T2) so that the substrate voltages and the cutoff voltages of the MOS transistors (T1, T2) of the transistor pair are influenced in the opposite direction.

    Abstract: Circuit for generating an inverse signal of a digital signal with minimal delay difference between the inverse signal and the digital signal. Two inverter circuits (6, 8; 7, 9) have been connected in series. The output signal of the second inverter circuit (7, 9) is the digital signal. An input signal for the first inverter circuit (6, 8) is supplied to a pass-through circuit (13, 14) with threshold action. The signal present between the first (6, 8) and the second (7, 9) inverter circuit is supplied to a control input (16) of the pass-through circuit with threshold action. The signal which is also present between the first (6, 8) and the second (7, 9) inverters appears with some delay at the output (17) of the pass-through circuit with threshold action, which signal is the inverse of the digital signal and at the same time constitutes the output signal of the pass through circuit (13, 14) with threshold action.

    Abstract: Integrated circuit chips with two or more multielement logic paths (A, B) can be made to exhibit virtually skew-free operation by setting the sum of the pull-up delays in one path equal to the sum of the pull-up delays in the other and by setting the sum of the pull-down delays in one path equal to the sum in the other. As a result, analog clock systems become feasible, process dependent race conditions are avoided, countdown circuits have reduced sensitivity to parameter fluctuation, and skewless inversions of clock signals are feasible.

The clock signal is split into two different clock signals. One of the clock signals is an inverted version of the other. A delay circuit is coupled to each of the clock signals. Each of the delay circuits generates a delayed version of the corresponding clock signal. A corrector circuit is coupled to receive both the delayed versions of the clock signals.

    Abstract: Techniques for providing improved memory flip-flops and other logic circuits are described. A flip-flop uses only one p-channel transistor (M14) to drive the output node strongly to achieve fast results. To reduce diffusion area, parallel logic is substantially eliminated and only series branches are used, in critical areas. This allows all pull-up transistors and/or all pull-down transistors to be formed from contiguous active areas. The D-to-Q path is reduced, and the clock is used to control the output. The clock becomes the dominant controller of the output when it is located closest to the output. Placing the clock devices (M35, M39-M40) closest to the clocked nodes reduces clock skew. The rising D response time and falling D response time are caused to be as close as possible to reduce the overall cycle time. To reduce parasitics in the circuit, complex-gates are used which are asymmetric. Even multiples of series branches per gate are used to share contacts and eliminate breaks in the layout diffusion. Adding complex-gates to a circuit while using asymmetric gates for smaller layouts achieves additional functionality. One component of the clock, along with the master drive circuit, is used to drive the slave latch of a flip-flop to avoid inserting additional gates into the logic of the fast output path. Reset and set circuitry is designed to be outside the critical path of the clock, and outside the slave latch, to provide rapid Q output response time to the clock and D inputs.

    Abstract translation: 描述了用于提供改进的存储器触发器和其它逻辑电路的技术。 触发器仅使用一个p沟道晶体管(M14)来强烈驱动输出节点以获得快速的结果。 为了减少扩散面积,基本上消除了并行逻辑,并且在关键区域仅使用串联分支。 这允许所有上拉晶体管和/或所有下拉晶体管由连续有效区域形成。 D-to-Q路径减少,时钟用于控制输出。 时钟成为最接近输出时输出的主要控制器。 最靠近时钟节点的时钟设备(M35,M39-M40)可以减少时钟偏移。 导致上升的D响应时间和下降的D响应时间尽可能接近以减少整个周期时间。 为了减少电路中的寄生效应,使用不对称的复门。 每个门的串联分支的倍数用于共享接触并消除布局扩散中的断裂。 在使用非对称门用于较小布局的同时向电路添加复合门可实现额外的功能。 时钟的一个组件以及主驱动电路用于驱动触发器的从锁存器,以避免在快速输出路径的逻辑中插入附加的门。 复位和设置电路被设计为在时钟的关键路径外部和从锁存器之外,为时钟和D输入提供快速的Q输出响应时间。
