The dissertation presents novel methodologies to realize a multi-band and multi-standard receiver with an interference-cancellation capability. First, the receiver specifications are derived from the wireless communication standard. These specifications are then used to obtain the required amount of TX leakage cancellation by using a proposed frequency selective feedback topology with multi-band capability. The effectiveness of this technique is demonstrated by the measurement of prototype integrated circuit (IC). To make the IC operate for multi-standard, another novel technique is also proposed for a channel-selection filter. With a proposed interpolated resistor bank, the active-RC channel-selection filter has programmable gain and pseudo-continuous bandwidth, which reduce the total power consumption and silicon area of the receiver. The measured result of a prototype silicon chip shows the effectiveness of the technique. With these two topologies, a multi-band multi-standard receiver that uses low power can be realized at a cost.
