摘要: Described are fast synchronous counters with reduced combinatorial logic. In one embodiment, a four-bit shift register is configured in a ring and preset with a data pattern (e.g., 1000). The register is then rapidly shifted into any of four unique states. Combinatorial logic connected to the shift register converts the four unique states into a two-bit binary signal representative of the four states. In the general case, counters in accordance with this embodiment represent N-bit binary numbers using 2N synchronous storage elements. Two or more counters can be combined to produce larger synchronous counters. An up/down counter in accordance with yet another embodiment is connected to a multi-path delay line to create a variable delay circuit. The switching speed of the delay circuit is independent of the number of delay settings. Also advantageous, the delay circuit scales linearly, in terms of power consumption and area, with changes in delay granularity.

摘要: A phase-locked loop circuit is constituted in such a manner that a delayed signal created by causing an input signal to loop through a delay stage a plurality of times is compared in terms of phase with the input signal, and an amount of delay in the delay stage is controlled in accordance with the comparison result of the delayed signal and the input signal. Therefore, the circuit size can be reduced with a reduced number of delay units constituting the delay stage.

摘要: Noise in a semiconductor device including a photo sensor is reduced. The semiconductor device includes an analog/digital converter and a photo sensor including a photodiode. The analog/digital converter includes an oscillation circuit and a counter circuit. A first signal output from the photo sensor is input to the oscillation circuit. The oscillation circuit has a function of outputting a second signal obtained by a change in oscillation frequency of the first signal. The counter circuit has a count function by which addition or subtraction is performed by a control signal with the second signal used as a clock signal. The counter circuit performs subtraction during the reset operation of the photo sensor. The counter circuit performs addition during the selection operation of the photo sensor. Thus, the output value of the analog/digital converter can be corrected.

摘要: Digital focal plane arrays (DFPAs) with multiple counters per unit cell can be used to convert analog signals to digital data and to filter the digital data. Exemplary DFPAs include two-dimensional arrays of unit cells, where each unit cell is coupled to a corresponding photodetector in a photodetector array. Each unit cell converts photocurrent from its photodetector to a digital pulse train that is coupled to multiple counters in the unit cell. Each counter in each unit cell can be independently controlled to filter the pulse train by counting up or down and/or by transferring data as desired. For example, a unit cell may perform in-phase/quadrature filtering of homodyne- or heterodyne-detected photocurrent with two counters: a first counter toggled between increment and decrement modes with an in-phase signal and a second counter toggled between increment and decrement modes with a quadrature signal.

摘要: The disclosed embodiments relate to an asynchronous down counter, which can be loaded with any value N and then decrement exactly N times. The counter comprises an array of cells, wherein each cell is configured to hold a digit in a redundant base-k representation of a number contained in the array of cells. Each cell further comprises a finite state machine that defines state transitions between states, where these states are held on wires and state transitions are synchronized between neighboring cells. Each cell is further configured to asynchronously borrow, if possible, from a more significant adjacent cell to increase a value of a digit in the cell. This asynchronous borrowing improves performance by ensuring that a decrement operation, which decrements a digit in a least significant cell in the array, will borrow from an adjacent more significant cell, without having to wait for the completion of a rippling sequence of borrows from more significant cells.
