20110095614 | SCALABLE HIGHEST AVAILABLE VOLTAGE SELECTOR CIRCUIT - A scalable highest available voltage selector circuit determines the highest of n input voltages and connects the highest voltage to an output. The circuit has at least n circuit branches, each of which comprises n−1 “comparator” FETs connected between an input voltage and an output node, and a diode-connected FET connected between the output node and a current source. The junction of the diode-connected transistor and current source provides a control signal used by the other branches. Each of a branch's comparator FETs have their gates connected to a respective one of the other branches' control signals, such that they are driven on regeneratively when the applied input voltage is the highest of the n input voltages. Each branch also includes n−1 “shorting” FETs connected across the diode-connected transistor, arranged to be driven off when the applied input voltage is the highest, but which are otherwise driven on. | 04-28-2011 |
20120313716 | TWO OSCILLATOR SYNCHRONIZATION SYSTEM - An oscillator synchronization system employs two oscillators, each of which includes an integrator which provides a ramping signal at its output, a comparator which receives the ramping signal and a reference signal at respective inputs and toggles an output when the ramping voltage crosses the reference signal, and a one-shot circuit that generates the integrator's reset signal when triggered. The system is preferably arranged such that the oscillators can be operated independently, in which case each oscillator's one-shot is triggered by its own comparator output, or synchronously, in which case each oscillator's one-shot is triggered by the other oscillator's comparator output—with the ramp signal of each oscillator operating to reset the integrator of the other oscillator. The oscillators are typically out-of-phase when synchronized, with the phase difference varying with the magnitude of the reference signals applied to the comparators. | 12-13-2012 |
