To V Srini, thank you for introducing me to the fascinating world of Receiver Systems. The accepted approach involves translating the signal from IF to DC by performing a complex mixing operation on the bit stream and performing decimation using structures similar to standard lowpass decimation filter architectures.

It is concluded that the folding and interpolation system in the video band achieves an even better performance than full-parallel converters implemented in a similar process and dissipating over 10 W. Thank you for your valuable inputs and comments on the material. This DC-offset gets superimposed on the desired signal in the baseband.

Next, the proposed complex image reject filter architecture is discussed. Figure a shows the block diagram of such a receiver. Several methods used to minimize the image interference include digital signal processing algorithms for estimation and correction of the errors due to mismatch and strategic choice of IF so as to place the interfering signals outside the image frequency range.

Discussed in section 1. Two new architectures are proposed. The convolution of the two impulse functions with the input spectrum yields a superimposition of the image signal component with the desired signal at if.

I would like to thank 3.

The output of the ADC is sent to a decimation filter section. I would like to thank 3. It achieves an excellent performance while dissipating only mW from a single 5-V power supply.

The precision requirements of each pipeline stage decrease through the pipeline i. Polyphase decomposition applied to FIR This architecture has been successfully implemented in a single chip receiver. The accepted approach is to do a complex mix on the bit stream, thus down converting the signal in frequency domain from IF to DC, followed by low pass filtering.

Structure of the pipeline analog to digital converter. The front end needs very high performance circuits and has been traditionally built with analog circuit design techniques.A Level-Crossing Flash Asynchronous Analog-to-Digital Converter topology for an asynchronous analog-to-digital converter, dubbed LCF-ADC, that has several major advantages over An analog-to-digital converter (ADC) is an integral part of the overall system, as it enables the sensor to interface.

Abstract There are many difierent types of ADC structures, one of these is the Pipelined ADC, which is characterised by having relative high speed, with a low area-. For applications where latency is critical (e.g. where the ADC is in the critical path of a closed loop), one is restricted to using a Flash or variant ADC.

A design tradeoff which exists for pipeline ADCs is the choice between a larger number of bits resolved per stage (hence less latency, but more design complexity), or a fewer number of bits.
