摘要： A re-configurable low noise amplifier utilizing feedback capacitors is disclosed. The low noise amplifier has output transistors, capacitor switch cells, and capacitance distributors all in an output portion. The output transistors are for controlling selection of a specific frequency band in a wide band of frequencies. The capacitor switch cells are for adjusting a harmonic frequency for the specific frequency band. The capacitance distributor is for determining an amount of gain, and according to the gain, an output impedance feeds back to an input portion of the low noise amplifier for input matching. Since the output portion is at high impedance and suitable for a wide band of frequencies, input matching not only makes the low noise amplifier applicable to kinds of wireless communication standards, but also fulfills high gain and low noise figure.

摘要： A communication apparatus and a low noise amplifying method. The communication apparatus includes a gain adjusting unit to adjust a gain of an input signal; a combiner to generate an output signal using the signal gain-adjusted at the gain adjusting unit; and a feedback unit which provides a feedback signal, which is generated using the output signal generated at the combiner, to an input stage. Accordingly, various frequency bands defined in the wireless standards can be supported. Since the load impedance is generated without resistance, the manufacturing cost and the product size can be reduced.

摘要： A semiconductor memory device and a system using the semiconductor memory device can perform a data sampling operation safely without a phase synchronization device such as delay locked loop (DLL) or phase locked loop (PLL), wherein the semiconductor memory device incorporates a strobe signal, which is synchronized with a data signal, both traversing similar-length paths between a memory device and a memory controller. In a read operation, the semiconductor memory device generates a first strobe signal synchronized with a read data signal, whereby a read data signal is outputted at both a rising and a falling edge of a strobe signal. In a write operation, a second strobe signal is generated whereby only a single edge is used to generate a write data signal, thereby allowing sufficient time for a data sampling operation to occur and thus operating at half the speed of a read operation.
