摘要： Systems and methods are provided for providing precision timing signals. A first register bank, driven by a first clock signal, provides a first delay along a first signal path. A second register bank, driven by a second clock signal related to the first clock signal, provides a second delay along a second signal path. A system control controls at least one of the first and second banks of registers to control the first and second delays, as to provide a desired skew between the output of the first signal path and the second signal path.

摘要： One embodiment of the present invention may include a programmable gain amplifier comprising an input multiplexer operative to sequentially select input signals for amplification. The input signals may be chosen from a plurality of input signals based on a selection signal. The programmable gain amplifier may include at least one amplifier gain stage operative to apply a variable gain amount to a selected input signal. The programmable gain amplifier may further include a gain mapping component that controls the variable gain amount for each of the selected input signals.

摘要： A system that has a pseudorandom number generator and a mapping system. The pseudorandom number generator generates a random number that is mapped by the mapping system to an output value that is selected from a set of predetermined output values. To increase the randomness of the sequence of numbers generated by the pseudorandom number generator, a tap and/or seed value of the pseudorandom number generator can be varied.

摘要： A deglitch circuit utilizes a first flip-flop coupled to the input signal and a second flip-flop coupled to the output of a circuit with feedback from the output to gates to control first and second inputs to the first flip-flop. In an alternative arrangement, a counter is provided between the output of the first flip-flop and the input to the second flip-flop in order to provide flexibility and the possibility of a longer delay for the circuit.

摘要： The formation of a semiconductor sensing device is disclosed, where the device can be used to sense pressure, for example. The device is formed by etching the entire backside of a semiconductor substrate or wafer. This streamlines the fabrication process by omitting a number of steps that would otherwise be required to selectively etch certain locations of the substrate. This also improves device performance and compactness by allowing associated support circuitry to be formed closer to a sensing region, and more particularly piezoelectric elements of the sensing region.

摘要： A control voltage window generator that tracks process, voltage supply, and temperature variations for a voltage controlled oscillator includes: a first transistor of a first conductivity type coupled between a supply voltage node and an upper control voltage node; and a second transistor of a second conductivity type coupled to the upper control voltage node to compensate for process variations in devices of the first conductivity type. Additionally, a target pull-in voltage generator includes circuitry for providing a pull-in control voltage that will always be inside the control voltage window, and also tracks process, voltage supply, and temperature variations.
