Abstract

A 28 nm CMOS multistandard TV tuner is presented. A power-efficient RF front end and >80 dB dynamic range ΔΣ ADC, together with a smart AGC algorithm, enable this tuner to achieve 64 dB ATSC A/74 N+6 ACI while dissipating only 180 mW. A baseband resistor weighting harmonic rejection mixer clocked by a 7-13.6 GHz PLL and single-edge-triggered shift registers achieves >58 dB harmonic rejection ratio at frequencies up to 827 MHz.
28nm CMOS 180 mW多标准电视调谐器
介绍了一种28纳米CMOS多标准电视调谐器。低功耗RF前端和>80 dB动态范围ΔΣ ADC,加上智能AGC算法,使该调谐器能够实现64 dB ATSC A/74 N+6 ACI,同时功耗仅为180 mW。由7-13.6 GHz锁相环和单边触发移位寄存器时钟的基带电阻加权谐波抑制混频器在高达827 MHz的频率下实现>58 dB的谐波抑制比。
