analog circuits content in radio transmitters and synthesizers, in favour of more digital circuits. But for radio receivers, a major amount of analog circuitry is still required [1,3]. This paper demonstrates the feasibility of further reducing the analog circuit content of a radio receiver, while maintaining acceptable performance. The circuit offers the main advantages of a digital design: after adding one (small) macroblock to a digital standard-cell library, the whole receiver can be described in an RTL language and can be realised with a standard digital design methodology. Porting or scaling to another silicon technology becomes relatively easy. Figure 25.1.1a shows the block schematic of a modern zero-IF radio receiver. Especially the analog filters tend to contain large capacitors and to occupy a major portion of the receiver’s silicon area. Furthermore, due to large signal gain in the Variable-Gain Amplifiers (VGA), signal offsets and self-mixing products
