Abstract: Capacitive coupling may enable more tightly synchronized operation of components in a multi-domain distributed driver that provides slope-controlled switching of differential signal lines. One illustrative distributed driver includes: a first set of transistors each coupled to drive a first bus line; a first set of delay elements configured to enable and disable the first set of transistors sequentially; a second set of transistors each coupled to drive a second bus line; a second set of delay elements configured to enable and disable the second set of transistors sequentially; and at least one capacitance coupling a first node in the first set of delay elements to a corresponding second node in the second set of delay elements to synchronize signal transitions at the first and second nodes.

Abstract: Circuits and processes for locking a voltage-controlled oscillator (VCO) at a high frequency signal are described. A circuit may include a voltage-controlled oscillator configured to generate a high frequency signal based on a control signal, a dummy load parallel to the voltage-controlled oscillator and configured to receive the control signal via a switch, and a digital-to-analog converter coupled to the voltage-controlled oscillator where the control signal is generated based on an output of the digital-to-analog converter.

Abstract: Circuits and processes for locking a voltage-controlled oscillator (VCO) at a high frequency signal are described. A circuit may include an adjustable current converter (ACC), coupled at an input terminal to a power source, operable to output a control signal (VC) at an output terminal. A first switch may be coupled to the ACC and to the VCO. The VCO, when in an “ON” state, receives the control signal and outputs a high frequency signal (VHF). A digital filter may be coupled to the VCO and operable to receive the VHF. Based on the VHF, the digital filter generates a data signal having a data value. The circuit may also include a digital-to-analog converter (DAC) operable to receive the data signal and, based on the data value, output an adjustment signal to the ACC. The ACC may adjust the control signal based on the adjustment signal received from the DAC.

Abstract: 3?5?-steroid compounds of general formula I is disclosed. These compounds are useful in the treatment of epilepsy or comorbidities associated with epilepsy or conditions associated with convulsions, such as seizures associated with hypoxia, seizures associated with traumatic brain damage, seizures associated with intoxication, pathological changes caused by hyperexcitation, or in treatment of conditions accompanying epilepsy, such as affective disorders, depression, post-traumatic stress disorder (PTSD) and stress-related diseases, anxiety, schizophrenia and psychotic disorders, related ischemic CNS damage, neurodegenerative changes and disorders, multiple sclerosis. The compounds of general formula I also show age-specific efficacy.
