摘要： A first constant voltage is supplied to a variable capacitance in a switched capacitor, and the variable capacitance is effectively charged to the first constant voltage in each cycle of a sampling clock. A current generated by charging the calibration resistance is averaged, and a resultant current is compared against a current generated by applying a second constant voltage to a resistance. The capacitance value of the variable capacitance is adjusted in accordance with a result of the comparison. Thus the variable capacitance is calibrated so as to have a target value.

摘要： Embodiments of the present invention relate generally to reconstruction filtering. In particular, embodiments enable highly linear, highly programmable, and easily reconfigurable reconstruction filters. Further, embodiments provide substantial power consumption, area, and cost savings compared to conventional solutions. For example, embodiments use all-passive filtering and substantially reduce active elements compared to conventional solutions. As a result, significant reductions in required area, noise, and power consumption can be achieved. In addition, embodiments perform filtering solely in the current domain, thereby eliminating the non-linear voltage-to-current conversion used in conventional circuits and enabling highly linear filtering. Furthermore, embodiments are highly programmable and easily reconfigurable without the use of tunable capacitors. As such, embodiments are very suitable solutions for multi-band multi-mode wireless transmitters.
