“…The resultant computations are often hard to carry out with analog circuits. For example, in the linear amplification with nonlinear components (LINC) [32]), it is necessary to generate drive signals and for an amplifier pair that are derived from the input signal using the relations and (4) The use of DSP allows computing the resulting signals in simple fashion, while it is difficult to do with analog electronics. 5) Signal cancellation: In a receiver, the elimination of signals corresponding to (intentional or unintentional) interferers is a central concern.…”

Digital logic integrated circuits are advancing toward ever higher speeds of operation. Clock frequencies already exceed 1 GHz in some Si CMOS-based consumer products, and even higher speeds are attainable in specialized technologies, such as those based on GaAs, InP, and SiGe bipolar and field-effect transistors. Digital approaches may be used to carry out a variety of functions important in microwave systems, including signal generation, filtering, and frequency conversion. The digital implementation provides a variety of potential benefits, including lack of sensitivity to aging and component inaccuracies, flexibility, and programmability. The dynamic range and degree of nonlinearity can be specified by design. Signal storage and memory functions are easily accomplished. Single-chip integration of digital and microwave systems are also facilitated. The application of digital techniques in domains previously considered to be analog is an important ongoing technology thrust, which may be expected to accelerate. Critical interfaces between the digital and analog domains are provided by analog-to-digital converters, digital-to-analog converters, and fractional-frequency synthesizers. This paper reviews the prospects of digital techniques for microwave systems, and briefly describes the state-of-technology and future possibilities. Index Terms-Analog-to-digital conversion, digital signal processing, digital-to-analog conversion, high-speed digital integrated circuits. I. INTRODUCTION S IGNAL processing (including amplification, filtering, frequency generation, frequency conversion, and modulation) at microwave frequencies has traditionally been carried out with analog circuits. However, digital circuits are steadily advancing in capabilities. The technology advances promise to allow digital techniques to be used at frequencies well into the microwave region.

“…To date, impressive results have been achieved only with realizations in InAlAs/InGaAs and SiGe bipolar with frequencies up to 100 GHz. In contradiction CMOS frequency dividers have achieved only maximum operation frequencies in the range of 10 GHz [1][2][3][4][5]. However, the fastest of these dividers use dynamic circuits [1], [2], injection-locked oscillators [3] or impractical modified logic [4], [5] which requires external biasing at the clock inputs for various signal levels.…”

“…Compared to the bipolar and III-V dividers, complementary metal-oxide semiconductor (CMOS) dividers usually operate at lower frequencies. To increase the operating frequency at a given power consumption, several techniques are used, such as injection-locking [3], dynamic circuit [4], and improved Miller dividers [5]. Compared with them, a static divider has a much wider operating range and moderate operating frequency and power consumption.…”
