Abstract: A method for testing a strip of MEMS devices, the MEMS devices including at least a respective die of semiconductor material coupled to an internal surface of a common substrate and covered by a protection material; the method envisages: detecting electrical values generated by the MEMS devices in response to at least a testing stimulus; and, before the step of detecting, at least partially separating contiguous MEMS devices in the strip. The step of separating includes defining a separation trench between the contiguous MEMS devices, the separation trench extending through the whole thickness of the protection material and through a surface portion of the substrate, starting from the internal surface of the substrate.

Abstract: A CMOS image sensor and method for making such a sensor includes a coating over the photosensing parts, wherein the coating performs a dual function. In fabrication, the coating prevents the formation of silicide, which is not optically opaque, on the photosensing parts. When the CMOS sensor is in use, the coating helps to couple light onto the photosensing parts, and therefore acts as an anti-reflective layer. The method of fabrication uses a self-aligning technique, which ensures pixel-to-pixel uniformity.

Abstract: An image sensor has an array of pixels read by column circuits to provide reset and read samples on a pair of sample capacitors. To alleviate the effects of parasitic capacitance in the region of the sample capacitors, a modified timing arrangement is used. Both sample switches are operated simultaneously to pre-charge both sample capacitors with a pixel signal value. One sample switch is operated after reset to apply a reset value to one of the pre-charged sample capacitors.

Abstract: A solid state image sensor has an array of pixels in which each column has a reset voltage line and a read line. The sensor is reset and read a row at a time, with reset-related values held in a frame buffer for subsequent subtraction from read values. Reset-related values are derived in each column by sampling the voltage during reset on one capacitor and the voltage on release of reset on a second capacitor, and differencing these values to provide an output for the frame buffer. This provides a reduction in the size of frame buffer which would otherwise be required.

Abstract: A CMOS output buffer uses feedback from a ground node to reduce ground bounce by utilizing a tolerable ground bounce limit, making it less sensitive to operating conditions and processing parameters. An input to the NMOS device of the output buffer is provided by the output of a control element which receives a first input from a pre-driver and a second input (i.e., the feedback) from the ground node.

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.
