    摘要: A detection circuit for receiving a pair of unstable input signals along a pair of input leads and providing a stable output signal along an output lead, preferably to downstream circuitry. The detection circuit includes a plurality of transistors including a first transistor and a second transistor, wherein at least one of the first and second transistors is configured to turn on upon the detection circuit receiving input signals along the pair of input leads. At least one of the first and second transistors is configured to provide a signal along a lead to circuitry which is configured to condition the output signal and turn on a third transistor. The third transistor is connected to the first and said second transistors such that when the third transistor turns on, the third transistor prevents the first and second transistors from turning on until a new clock signal is received by the detection circuit. Thus, the third transistor generally prevents any new input signals received along the input leads from propagating substantially through the detection circuit. Large differential hysteresis prevents small signals from propagating. The third transistor effectively limits the time period for decision making.

    摘要: An on-chip voltage reference supply operates in the current domain rather than the voltage domain, implemented with a single diode drop to reduce power supply headroom requirements. A plurality of current generators generate currents representing a first design voltage. A gain circuit responds to the currents to supply a gain voltage representing the sum of the first design voltages. A summing circuit sums the gain voltage and a second design voltage to derive the predetermined reference voltage.

    摘要: A sample and hold in a switched capacitor circuit with frequency shaping. The sample and hold does not require a pair of large area, power-consuming operational amplifiers and, as such, consumes less power and less area. Preferably, the sample and hold is operable in four different states wherein a different set of switches are closed in each of the four states. The switches are controlled by two clock signals and a plurality of signals derived from the two clock signals, such as four signals derived from the two clock signals. Desirably, the sample and hold with frequency shaping is configured to sample a voltage across a first capacitor while a second capacitor is disconnected from said first capacitor, and is configured to thereafter connect the second capacitor to the first capacitor and possibly discharge at least a portion of a charge held in the first capacitor into the second capacitor.

    摘要: A built in self test circuit for testing an analog to digital converter. An up counter receives a test input and a first clock signal and provides and upper limit. A down counter receives the test input and the first clock signal, and provides a lower limit. A digital to analog converter receives the test input and a second clock signal, and provides an analog output. Circuitry provides the analog output and a third clock signal to the analog to digital converter, and the analog to digital converter thereby produces a digital signal. An upper limit comparator receives the upper limit and the digital signal, and provides an upper limit status signal indicating whether the digital signal violates the upper limit. A lower limit comparator receives the lower limit and the digital signal, and provides a lower limit status signal indicating whether the digital signal violates the lower limit.
