摘要： A true random number generator (RNG) has one or more oscillators and an output register for storing a random number output. Each of the oscillators is activated, successively, in a free-running oscillation phase, and a capture phase during which the oscillator is quiescent. The output register latches during the capture phase of each oscillator an end state of that oscillator at or close to the end of its oscillation phase. The random number output is derived from the latched end states.

摘要： A band gap reference voltage generator has first and second current conduction paths between a first node and a second node. The first current conduction path has first resistive elements in series with a first forward-biased PN junction element. A tap is connected selectively to the first resistive elements through switches that are controllable to select a voltage divider ratio at the tap. The second current conduction path includes a second resistive element in series with a second PN junction element of greater current density than the first PN junction. A voltage error amplifier has inputs connected to the tap and the second PN junction element, and an output for providing a thermally compensated output voltage VREF. A feedback path applies the output voltage VREF through a third resistive element to the first node.

摘要： An electrical system can selectively power a load via a USB connection or via another power source, such as a wireless power transfer path. An integrated switch controller determines whether to power the load via the USB connection or the other power sources and controls two external transistors via a single I/O pin connection to implement that determination. The switch controller determines the greater of two voltages: a voltage associated with the USB connection and a voltage associated with the other power source. The switch controller also determines whether there is a valid USB connection. The switch controller circuitry that controls the two external transistors is powered at the greater voltage to ensure that the external transistors are appropriately and securely turned on or off.

摘要： A rail to rail differential buffer input stage includes n-type and p-type input differential transistor pairs connected in voltage follower configuration to the power supply rails. A reference voltage generator includes a reference differential transistor pair generating a dynamic reference voltage relative to the common mode input voltage. Dummy n-type and p-type transistor pairs have current conducting paths connected in parallel with the input differential pairs and are controlled by the dynamic reference voltage to divert supply rail current away from and deactivate one of the associated input differential pairs when the common mode input voltage is further from the dynamic reference voltage than a threshold value. Both the dummy pairs conduct and both the input differential pairs are activated when the common mode input voltage is closer to the dynamic reference voltage VB than the threshold value so that the overall transconductance of the buffer input stage remains constant.
