Abstract: A single-ended data transmission system transmits a signal having a signal voltage that is referenced to a power supply voltage and that swings above and below the power supply voltage. The power supply voltage is coupled to a power supply rail that also serves as a signal return path. The signal voltage is derived from two signal supply voltages generated by a pair of charge pumps that draw substantially same amount of current from a power supply.

Abstract: Disclosed is receiver for a noise limited system. A front-end circuit amplifies and band-limits an incoming signal. The amplification increases the signal swing but introduces both thermal and flicker noise. A low-pass band limitation reduces the thermal noise component present at frequencies above what is necessary for correctly receiving the transmitted symbols. This band limited signal is provided to the integrator circuit. The output of the integrator is equalized to reduce the effects of inter-symbol interference and then sampled. The samples are used to apply low frequency equalization (i.e., in response to long and/or unbalanced strings of symbols) to mitigate the effects of DC wander caused by mismatches between the number of symbols of each kind being received.

Abstract: A first non-volatile memory may store first data and a second non-volatile memory may store second data. An authentication component may be coupled with the first non-volatile memory and the second non-volatile memory and may receive a request to perform an authentication operation. In response to the request to perform the authentication operation, the authentication component may access the first data stored at the first non-volatile memory and the second data stored at the second non-volatile memory and determine whether the second data stored at the second non-volatile memory has become unreliable based on a memory disturbance condition. In response to determining that the second data stored at the second non-volatile memory has become unreliable, a corrective action associated with the first data stored at the first non-volatile memory may be performed.

The output stage includes a resistance disposed within the second IC device and having a first terminal coupled to a drain terminal of a transistor within the input stage via a first signaling line that extends between the first and second IC devices.

Abstract: A communication system comprises a transmitter and a receiver that communicate differential phase modulated data over a wireline channel pair. The transmitter encodes data symbols by generating first and second data signals with differentially phase shifted signal transitions with respect to one another. The receiver receives the first data signal and the second data signal and samples the first data signal based on a signal transition timing of the second data signal to generate a first output data symbol. The receiver furthermore samples the second data signal based on signal transition timing of the first data signal to generate a second output data symbol.

Abstract: An integrated-circuit output driver generates, in response to an input signal constrained to a first voltage range, a control signal at one of two voltage levels according to a data bit conveyed in the input signal, the two voltages levels defining upper and lower levels of a second voltage range substantially larger than the first voltage range. The output driver generates an output-drive signal constrained to a third voltage range according to the one of the two voltage levels of the control signal, the third voltage range being substantially smaller than the second voltage range.

Abstract: In a chip-to-chip signaling system includes at least one signaling link coupled between first and second ICs, the first IC has an interface coupled to the signaling link and timed by a first interface timing signal. The second IC has an interface coupled to the signaling link and timed by a second interface timing signal that is mesochronous with respect to the first interface timing signal. The second IC further has phase adjustment circuitry that adjusts a phase of the second interface timing signal using a digital counter implemented with Josephson-junction circuit elements.

Abstract: The embodiments herein describe technologies of cryogenic digital systems with a first component located in a first cryogenic temperature domain and a second component located in a second cryogenic temperature domain that is lower in temperature than the first cryogenic temperature domain. An electrical conductor is coupled between the first component and the second component along a first plane. The electrical conductor carries a signal between the first component and the second component. A cooling assembly is coupled to a segment of the electrical conductor. The cooling assembly may include an electrical insulator including ceramic material. The cooling assembly may include a cold plate, two cold plates, or an orthogonal cold strip.
