Integrated TV tuner design for multi-standard terrestrial reception

Digital TV reception is becoming increasingly important for both fixed and mobile equipment, be it TV sets or cellular phones. However, the continuing analog TV broadcast service poses additional challenges for tuner receivers. This paper presents issues and trends for monolithic tuner design. It describes the reception requirements and possible architectures for various standards and channel conditions. Critical block design is addressed with examples from practical implementations. Primarily, the design is geared toward maximizing the system dynamic range (from -85 dBm to +5 dBm desired input signal power) and multi-standard functionality. In addition, gearing toward mobile reception, trade-offs to reduce power consumption are also discussed.
