20080272809 | Integrated circuit power-on control and programmable comparator - An integrated circuit is provided with a main supply rail and a virtual supply rail connected by strong and weak header transistors. A power-on controller controls the switching on of the strong transistors after the virtual supply rail voltage has already been driven up to close to its operating level by the weak transistor. The power-on controller comprises a comparator monitoring a single reference voltage level with its output being latched within a latch and used to switch on the strong transistor. The comparator may be programmable to detect multiple different trigger voltage levels by using opposing charging and discharging transistors with one set of these operating in a saturated regime and the other in a regime in which the current therethrough varies in dependence upon the voltage being sensed. These opposing transistors can be used to charge or discharge a node with the state of that node being taken to generate the sensed output. | 11-06-2008 |

20090066164 | Power Controlling Integrated Circuit Cell - A power controlling integrated circuit cell is provided within an integrated circuit power grid to selectively couple an unswitched power supply input to a switched power supply output. The power controlling integrated circuit cell also includes a power control signal input and a power control signal output for supporting the distribution through the integrated circuit of the power control signal. The power controlling integrated circuit cell has a power switching circuit responsive to a power control input signal received at the power control signal input to selectively connect the switched power supply output to the unswitched power supply input, and a power control signal buffer circuit responsive to the switched power supply output to drive a power control output signal from the power control signal output. | 03-12-2009 |
20120286858 | Integrated circuit, method of generating a layout of an integrated circuit using standard cells, and a standard cell library providing such standard cells - An integrated circuit, a method of generating a layout of such an integrated circuit using standard cells, and a standard cell library providing such standard cells, are disclosed. The method of generating the layout comprises forming a plurality of rows, and populating each row with a plurality of standard cells chosen in dependence on the functional components required by the integrated circuit, each standard cell having its abutment area abutting the abutment area of at least one adjacent standard cell in the row. Within each row, each standard cell in that row is arranged to have a voltage connection area that is aligned with a common routing track, but with each standard cell having its voltage connection area configured so as not to extend across the entire width of the standard cell. Within each row, for each standard cell in the row, the voltage connection area of that standard cell is then connected to one of a plurality of voltage supplies having regards to a voltage requirement of the corresponding functional component defined by the standard cell, and independent of the voltage supply to which each adjacent cell in the row is connected. This provides a particularly flexible mechanism for placing standard cells during the layout operation, since standard cells that are required to run off the same voltage supply no longer need to be placed together. | 11-15-2012 |

20140035661 | AN INTEGRATED CIRCUIT AND METHOD FOR CONTROLLING LOAD ON THE OUTPUT FROM ON-CHIP VOLTAGE GENERATION CIRCUITRY - An integrated circuit and method are provided for controlling variation in the voltage output from on-chip voltage generation circuitry. The integrated circuit comprises voltage generation circuitry configured to operate from a supplied input voltage and to generate at an output node an on-chip voltage supply different to the supplied input voltage. A circuit block is then arranged to receive the on-chip voltage supply generated by the voltage generation circuitry, during operation of the circuit block the circuit block presenting a varying load on the output node. Oscillation circuitry is also coupled to the output node to provide an additional load on the output node, and is configured to produce an oscillation signal whose frequency varies as the value of the on-chip voltage supply varies. Control circuitry is configured to be responsive to a trigger condition to adjust the additional load provided on the output node by the oscillation circuitry. This provides a particularly simple and effective mechanism for providing an additional load on the output node which can be altered with the aim of offsetting variation in the load on the output node presented by the circuit block, thus allowing the variation in the voltage output from the on-chip voltage generation circuitry to be controlled. | 02-06-2014 |
