Abstract: Circuitry to provide a supply voltage. A voltage regulator is coupled to receive a target reference signal. The voltage regulator generates a supply voltage (Vtt) and is coupled to receive the supply voltage as an input signal. An upper limit comparator receives an upper limit voltage signal that is higher than the target reference voltage signal and the supply voltage to generate a “too high” signal when the supply voltage exceeds an upper threshold. A lower limit comparator receives a lower limit voltage signal that is lower than the target reference voltage signal and the supply voltage to generate a “too low” signal when the supply voltage is below a lower threshold. A pull up current source is coupled to pull the supply voltage up in response to the too low signal. A pull down current source is coupled to pull the supply voltage down in response to the too high signal.

Abstract: According to embodiments of the subject matter disclosed in this application, a wide input common mode sense amplifier may include a level shifter stage and an amplifier stage. The level shifter comprises a CMOS differential amplifier that has a rail-to-rail input common mode range. The level shifter accepts two input signals with a common mode voltage in a rail-to-rail range and produces two output signals with a stable common mode voltage. The differential amplifier amplifies the two output signals from the level shifter stage with high gain. The disclosed sense amplifier may be used to measure delay between two discrete time events.

Abstract: Systems or methods of the present disclosure may provide a dual bump design to support both high voltage input/output (HVIO) connections and medium speed input/output (MSIO) connections. The present disclosure includes an MSIO lane that couples to a first bump that couples to MSIO pins, a second bump that couples to an HVIO circuit, and a ball grid array (BGA) ball. The present disclosure also includes a multiplexer that selectively couples the MSIO pins to the BGA ball or the HVIO circuit to the BGA ball based on user input. As such, the MSIO lane may provide MSIO connections, HVIO connections, or both.

Abstract: Systems or methods of the present disclosure may provide protection to gate-driving circuitry from anomalous electrical conditions. A method may include detecting an anomalous electrical condition at an input/output (I/O) terminal of an electrical component. The method may also include determining whether the anomalous electrical condition comprises an undershoot condition or an overshoot condition. Additionally, the method may include generating a bias voltage based on the determination that the anomalous electrical condition comprises the undershoot condition or the overshoot condition and applying the bias voltage to the I/O terminal of the electrical component.

Abstract: A system and method for processing signals determines rise and fall times of a driving signal, compares the rise and fall times to desired values, and independently controls the rise and fall times to equal the desired values. The rise and fall times may be controlled by generating one or more first correction bits based on a difference between the rise time and a corresponding one of the desired values, generating one or more second correction bits based on a difference between the fall time and a corresponding one of the desired values, and then separately applying the bits to independently control the rise and fall times of the driving signal. The driving signal may be an I/O signal or another type of signal.
