Abstract
High-Q filters are a critical component in many systems. However, high-Q filters require very low-loss passive elements that are not compatible with monolithic technology. Therefore, filters are often implemented as off-chip components. Tunable high-Q filters require even larger space and weight, and are usually quite bulky. Active filters have been proposed in the past for a monolithic implementation. However, it is not easy to fulfil such requirements as a high dynamic range, low power consumption, low noise, wide tunability, stability, etc. With this study, we propose a survey of the main solutions presented in the literature, investigating the fulfilment of all or most requirements and their potential applications and feasibility, to be used in practical applications.
