| Wideband amplifiers are used in many radio frequency (RF) and high-data rate communication systems including satellite transceivers, pulsed radar systems, optical receivers, etc. For such applications, a distributed amplifier topology is often used because it can overcome the classical amplifier gain-bandwidth tradeoff by combining the outputs from several active gain elements in an additive fashion. A MATRIX amplifier is a 2-dimensional amplifier taking advantages of additive mechanism of distributed amplifiers and multiplicative of cascaded amplifiers. The MATRIX amplifier is potentially better choice in many applications since it has a higher gain per cell than the distributed amplifier while it maintains the bandwidth of the distributed amplifier.; The burgeoning demand for CMOS system-on-chip (SOC) solutions has spawned intense worldwide research on CMOS RF integrated circuits. Unfortunately, the mundane issue of parasitics associated with active components that are inferior to their GaAs and SiGe counterparts, and on-chip passives on lossy silicon substrates has impeded development. In fact, without an optimization technique, many RF circuits in fine-line CMOS technology are virtually impossible to design owing to the frequency-dependent non-linear parasitics. To achieve optimum performance from CMOS RF and analog ICs, a new parasitic-aware design technique is proposed. |
