Abstract: A variable phase amplifier circuit is disclosed and its method of use in tuning devices having resonators. The variable phase amplifier receives an input differential signal pair. The input differential signal pair can be generated by a resonator device. The variable phase amplifier generates a modified differential signal pair in response to receiving the input differential signal pair. The variable phase amplifier provides a means to vary the phase of the modified differential signal pair with respect to the input differential signal pair, in an accurate and stable manner. If the modified differential signal pair with a phase shift introduced in it is fed back to the resonator device, the resonator will change its frequency of oscillation, where the new frequency of oscillation is a function of the phase of the modified differential signal pair.

Abstract: The disclosed power-on reset circuit provides an indication of when and whether a supply voltage Vdd has reached a trigger voltage level Vtrig. The disclosed circuit includes a flip-flop circuit and a first comparator circuit. The circuit according to the invention has a D input node of the flip-flop circuit coupled to the supply voltage. The first comparator circuit outputs a clock signal, where the flip-flop circuit is clocked by the clock signal. A Q output node of the flip-flop circuit provides the power-on reset signal, where the power-on reset signal is in a LO state when the supply voltage is at a voltage level that is less than the trigger voltage level Vtrig. The power-on reset signal is in a HI state when the supply voltage is at a voltage level that is greater than the trigger voltage level Vtrig.
