Abstract: A digital frequency divider has a single circulating shifter register loaded with a bit sequence of variable length and having two outputs adjacent such that are output is equal to the other delayed by one clock period. The outputs are passed to a multiplexer via further logic, the multiplexer selecting one of two inputs depending on whether a clock is high or low. Program logic is provided so that the circuit is configurable for odd, even or half integer division by detecting changes in the bit sequence between 0 and 1 and selectively nulldeletingnull the first half clock cycle when a change is detected. This allows even, odd or half integer clock division with an nullevennull mark space ratio.

Abstract: A solid state image sensor includes an array of pixels and a corresponding array of microlenses. The positions of the microlenses relative to their corresponding pixels may vary according to the distances of the pixels from a central optical axis of the image sensor to substantially eliminate vignetting of light collected by the microlenses.

Abstract: There is disclosed a method and circuit for allowing access to a shared memory by at least two controllers having different bus widths. Such method and circuit provides particular advantages in its application to controlling access to a shared memory in a digital set-top-box of a digital television receiver. An arbiter is provided to access between memory accesses by first and second memory access circuitry. The first memory access circuitry accesses a block of data in the shared memory, and the second memory access circuitry accesses two blocks of data in each memory access. Each second memory write access comprises reading blocks of data from first and second memory locations and then writing blocks of data to first and second memory locations.

Abstract: An AC capacitor is coupled to a totem-pole type PFC circuit. In response to detection of a power input disconnection, the PFC circuit is controlled to discharge the AC capacitor. The PFC circuit includes a resistor and a first MOSFET and a second MOSFET coupled in series between DC output nodes with a common node coupled to the AC capacitor. When the disconnection event is detected, one of the first and second MOSFETs is turned on to discharge the AC capacitor with a current flowing through the resistor and the turned on MOSFET. Furthermore, a thyristor may be simultaneously turned on, with the discharge current flowing through a series coupling of the MOSFET, resistor and thyristor. Disconnection is detected by detecting a zero-crossing failure of an AC power input voltage or lack of input voltage decrease or input current increase in response to MOSFET turn on for a DC input.

Abstract: A control system includes a mirror controller generating horizontal and vertical mirror synchronization signals for a mirror based upon a mirror clock signal. Laser modulation circuitry generates horizontal and vertical laser synchronization signals as a function of first and second laser clock signals and generates control signals for a laser that emits a laser beam that impinges on the mirror. First synchronization circuitry receives the horizontal mirror synchronization signal and the horizontal laser synchronization signal, and modifies generation of the first laser clock signal to achieve alignment between the horizontal mirror synchronization signal and horizontal laser synchronization signal. Second synchronization circuitry receives the vertical mirror synchronization signal and the vertical laser synchronization signal, and modifies generation of the second laser clock signal to achieve alignment between the vertical mirror synchronization signal and vertical laser synchronization signal.
