摘要： A power-on reset circuit with glitch sensing capabilities is formed as part of the same integrated circuit chip containing other logical circuits. A port included in the integrated circuit chip enables a power-on reset signal generated by the integrated power-on reset circuit to be output from the chip and applied to other chips installed in a single chip or multi-chip electronic system. The power-on reset circuit compares a capacitor stored reset voltage to a reference voltage and outputs the power-on reset signal when the reset voltage falls below the reference voltage. Storage of the reset voltage by the capacitor is controlled by a glitch sensor which detects changes in voltage provided by a power supply in excess of a given threshold and, in response thereto, triggers a capacitor discharge. This causes the reset voltage to fall below the reference voltage, and the power-on reset signal to be output. Furthermore, for synchronously operated systems, the output power-on reset signal is synchronized with an edge of an output clock signal.

摘要： Aspects of a method and system for sharing filters between transmit and receive paths in an integrated FM radio are provided. In this regard, a FM radio receive processing path and a FM radio transmit processing path may each be configured to share a filter. Accordingly, one or more switching elements may enable coupling/decoupling the filter to/from the FM radio transmit and FM radio receive processing paths. Furthermore, the switching elements may be programmatically controlled by a processor and/or memory. Additionally, by coupling the filter to the transmit receive paths during alternating time intervals, aspects of the invention may enable simulating simultaneous transmission and reception of FM radio signals utilizing while sharing one or more filters. In various embodiments of the invention, separate filters may be utilized for an in-phase processing path and a quadrature phase processing path.

摘要： A method and system for buffering a clock signal is provided. The method may include self-biasing a PMOS transistor of a buffer, utilized for amplifying an in-phase/quadrature phase signal, to produce a first bias voltage at the gate of a PMOS transistor, and biasing an NMOS transistor of the buffer via a controllable current source to produce a second bias voltage at the gate of the NMOS transistor. The gain of the buffer may be controlled by varying a controllable current source coupled to a second NMOS transistor configured as a diode. Two coupling capacitors may be utilized to remove a DC component of the signal. Multiple buffers may be coupled end-to-end to increase the overall drive capability, where the channel width of the transistors within the transistors may be doubled in each successive buffer.

摘要： Embodiments of the present invention provide an oscillator circuit having a steady output frequency that is independent of the supplied voltage. This oscillator includes a Schmitt trigger circuit which may be implemented within an integrated circuit of a wireless terminal or other like portable electronic device. The Schmitt trigger circuit receives a threshold voltage input and a second voltage input. The Schmitt trigger circuit generates an output voltage equal to either a first output voltage or a second output voltage based on the results of comparing the threshold voltage input to the second voltage input. An RC network may be coupled to the output of the Schmitt trigger circuit and is operable to supply the second voltage input to the Schmitt trigger circuit. A voltage divider network also couples to the output of the Schmitt trigger circuit wherein the threshold voltage input is proportional to the first output voltage reduced by the voltage divider network based on the output voltage of the Schmitt trigger circuit.
