摘要： A reference signal generating circuit, an AD conversion circuit, and an imaging device are provided. A clock generating unit includes a delay section including delay units, each of which delays an input signal and outputs a delayed signal, and outputs a low-order phase signal based on a signal output from the delay section. A high-order current source cell unit includes high-order current source cells, each of which generates the same constant current. A low-order current source cell unit includes low-order current source cells weighted to generate constant currents having current values that differ by a predetermined proportion of a current value of the constant current generated by the high-order current source cell. Selection of the high-order current source cell is performed based on a clock obtained by dividing a clock based on the low-order phase signal.

摘要： A controller sets a selector register of programmable delay signal logic is to a value equal to a required number of clock cycles of delay for signals output from an integrated circuit to an external memory. The controller controls a selection of additional logic along the output path to perform on the delayed signal within a clock cycle without any latency added to the output path by delay signal logic outputting the delayed signal. The controller waits required number of clock cycles after setting the selector register before using the delayed signal output by the delay signal logic onto an output path.

摘要： A delay buffer includes a first shift register receiving input data and having a shift signal input port. The first shift register right shifts the input data responsive to a shift signal on the shift signal input port. The shift signal is determined based on an effective bit width of the input data. A first delay line receives the shifted data from the first shift register while a second delay line of equal length to the first delay line receives the shift signal. A second shift register receives the output from the first delay line and receives the output of the second delay line on a shift signal input port. The second shift register then left shifts the data contained therein according to the shift signal.

摘要： Circuitry for use in aligning bytes in a serial data signal (e.g., with deserializer circuitry that operates in part in response to a byte rate clock signal) includes a multistage shift register for shifting the serial data signal through a number of stages at least equal to (and in many cases, preferably more than) the number of bits in a byte. The output signal of any shift register stage can be selected as the output of the “bit slipping” circuitry so that any number of bits over a fairly wide range can be “slipped” to produce or help produce appropriately aligned bytes. The disclosed bit slipping circuitry is alternatively or additionally usable in helping to align (“deskew”) two or more serial data signals that are received via separate communication channels.
