Abstract : This chapter addresses modern telecommunication
integrated circuits from the synthesizer focal point; in particular it
concentrates at the analysis and the design of integrated charge pump
circuit blocks. It presents an overview of charge pump topologies in
addition to a coherent analysis of the associated benefits and
shortcomings of all circuit alternatives. Moreover a novel favorable
charge pump combining current steering techniques with well utilized
unity gain buffers in a novel, noiseless feedback scheme, is introduced
to improve on switching speed, inherent charge pump ac noise, dead-zone
interval, therefore overall steady state aliased loop noise; while on
the other hand this charge pump exhibits superb DC matching
characteristics in a wide output voltage range. Furthermore a well
documented estimation of the active devices that contributes mostly to
the overall charge pump noise performance is presented. Also an
associated mathematical analysis concerning the frequency content of the
charge pump noise current is given. This proposed topology manifests its
applicability to charge pump alternatives, as it is demonstrated by the
associated simulation results from a 0.18μm design. Because of the
low-noise and accurate properties of this improved charge pump, it is
ideally suited to modern telecommunication standards synthesizer
realizations.
