    Abstract: Systems and methods for demodulating a plurality of contiguous channels contained within a bandlimited portion of a radio-frequency (RF) input signal are provided. In an embodiment, the bandlimited portion of the RF input signal is down-converted to baseband. After down-conversion, the bandlimited portion overlaps at baseband with a mirror image of the bandlimited portion. The plurality of contiguous channels within the down-converted signal similarly overlap at baseband and subsequently occupy a bandwidth substantially equal to half that required before down-converting. Image rejection is performed in the digital domain to recover each of the plurality of overlapping channels.

    Abstract: A memory module system may include a serial presence detect (SPD) memory and a memory controller. The SPD memory may store first SPD data and second SPD data of a memory module. The SPD memory may be partitioned into at least two regions that may operate as multiple SPD ROMs. The memory controller may boot the memory module system based on a comparison between the first SPD data and the second SPD data when an initialization signal is input to the memory module system. The memory module system may be booted stably and may prevent system breakdowns.

    Abstract: A transconductance device has substantially linear characteristics. The transconductance device includes a differential pair that receives a differential input voltage signal and produces a differential output current signal and a current source coupled to the differential pair. The current source produces a current having a constant portion and a variable portion, such that the derivative of the transconductance with respect to the differential input voltage is constant across a very large range of the differential input voltage and across a very high range of frequencies of the differential input signal. This linearization technique produces no extraneous noise at the differential output current.

    Abstract: A disclosed exemplary embodiment is a phase locked loop comprising a main charge pump driven by a phase error signal, and providing a first input to a loop filter. An auxiliary charge pump driven by the phase error signal feeds a second input of the loop filter. The loop filter can be an active loop filter comprising an operational amplifier and a feedback RC network. The first input of the active loop filter can be an inverting input of the operational amplifier and the second input can be a non-inverting input of the operational amplifier. An on-chip stabilizing capacitor fed by the auxiliary charge pump and coupled to the second input of the loop filter is significantly smaller than the conventional stabilizing capacitors. The loop filter outputs a regulating voltage for regulating the oscillation frequency of a voltage controlled oscillator in the phase locked loop.
