“… Reference [43] demonstrates a 2x32 MHz-BW tuner able to receive 8 to 10 contiguous RF channels in the 42 -1002 MHz. It integrates in a 65nm CMOS process a variable-gain LNA, harmonic-reject mixer helped by an RF tracking filter, a 5th-order Butterworth anti-aliasing filter, a baseband VGA I/Q pair, a 11-bit 175 MSps ADC I/Q pair, a low-noise PLL, a digital offset-correction loop, a digital image-correction, and digital individual channel selection.…”

“…As it receives two blocks of four channels, the dual low-IF receiver presented in [43] can only receive 8 channels located around two different RF frequencies. In case of channel bonding for high-speed internet, this statistically reduces the spectrum efficiency that cable operators can reach.…”

In this paper, a 50-300 MHz CMOS Gm-C tracking low-pass filter has been presented to resolve a local oscillator harmonic-mixing problem for Advanced Television Systems Committee terrestrial and cable digital TV tuner integrated circuits. A Gm-C filter based on parallel operation of a transconductor biased in the saturation region with source degeneration and a transconductor biased in the triode region is chosen to achieve high linearity performance at the VHF/UHF frequency bands. The cutoff frequency of the proposed filter is tunable from 50 MHz to 300 MHz. The filter is implemented in a 0.18 μm CMOS technology and achieve a minimum input-referred noise density of 3 nV/√Hz and maximum in-band output-referred third-order intercept point of 20.7 dBm. It operates at a nominal supply voltage of 1.8 V with bias currents of 114 mA. The active die area is 1.1 mm 2 .

“…In addition, these tuners suffer from image rejection and down-conversion of unwanted channels with LO harmonics. Alternatively, Docsis3.0 100MHz wideband tuners [2] reduce cost and power constraints but limit the frequency agility for cable operators [3]. In addition, the image rejection problem is exacerbated by the wider IF bandwidth.…”

This paper presents a broadband fully integrated high dynamic range RF front-end with a single-inductor programmable RF amplitude equalizer, 45dB variable gain range, 4.5dB NF, 60dB CSO/CTB, and 25dB anti-aliasing protection. It is designed in a 40GHz-ft BiCMOS 0.25µm process, consumes 400mW from a 3.3V supply, and enables a cable full-spectrum receiver to capture >16 channels over an 50MHz-1GHz RF band.
