Title: Tuner with switchable filters for removal of spurious inputs
Inventor: COWLEY NICHOLAS PAUL
IPC: H04B1/26
Filed: 2004-06-05
Abstract: A digital terrestrial tuner has an RF input 1 connected to a filter arrangement 2 whose output signal is supplied to a zero intermediate frequency (zero IF) frequency changer 7 - 10. The filter arrangement 2 comprises a plurality of signal paths 23 - 26 of different frequency responses, selectable one at a time for insertion between the tuner input 1 and the frequency changer 7 - 10. At least one of the signal paths includes a filter, e.g. low pass filter 30, which may be a fifth order elliptic filter and which attenuates out-of-band signals so as to reduce harmonic mixing products produced between these signals and harmonics of the frequency changer commutating signal. Similarly, high pass filter 32 attenuates harmonics of spurious signals at lower frequencies and reduces products formed by mixing with these. None of the filters is a tracking filter and no alignment is needed, either during manufacture or in operation.

Title: Current sensing and overload protection of a switch mode power converter
Inventor: RYAN PAUL THOMAS
IPC: H02H7/12
Filed: 2007-04-26
Abstract: A bi-level current sense circuit comprises two voltage comparators 808a,808b that have different respective thresholds TH1,TH2, and share a single current sense input 806 connected to a current generator 804 and via a resistor Rp to a current sense resistor Rs. The two bi-level current level thresholds can be set independently by the current sense Resistor Rs and the series resistor Rp, without changing thresholds TH1,TH2. The current level thresholds can be set by selecting the values of resistors Rp and Rs. The current sense circuit can be used to detect the current trough a switch 204 and a magnetic storage device 202 of a resonant discontinuous forward power converter (RDFC) where the comparators are connected to a switch controller 810 that can select a high or a low power mode in response. Over current protection can be provided by sensing a combination of current flowing in a winding of the magnetic storage device and a rate of change of that current. A series capacitor (fig 9, Cff) and a potential divider (fig 9, R2,R3) across the current sense resistor provide a signal combining current with its rate of change. When the combined sense signal exceeds a threshold the on time of the switch can be reduced to reduce an average power input to the magnetic device.
