“…This paper presents a small form factor -C-based CTF with the cutoff frequency tunable from 1.6 to 3.2 GHz, a linear phase response, high-output third-order intercept point (OIP3) and a wide dynamic range. Some of the features of this filter are presented in [6]. This paper introduces new data on reference current generation circuits for filter biasing, the test chip's output buffer design and presents the circuits for filter input signal normalization, namely, gain and offset control.…”

A sixth-order low-pass -filter for fiber-optic electrical dispersion compensation receivers cascades three biquads permitting a reduction of group delay variation down to 10 ps. A cutoff frequency is tuned from 1.6 to 3.2 GHz by using two methods, namely, changing and switching a CMOS varactor's polarity. Output third-order intercept point reaches 13.1 dBm and total harmonic distortion is below 40 dB at 0.9 -di output. The continuous time filter is implemented in a 0.18-m SiGe process, it occupies 0.17 mm 2 on a 3.2 3.7 mm 2 test chip and consumes 0.3 W from a 3.3-V supply.Index Terms-Active filter, antialiasing filter, continuous time filter (CTF), -filter, high-speed integrated circuit, optical fiber dispersion compensation.

“…As of today, the highest cut-off frequency low-pass continuous time analog filters are in the frequency band of 1 to 3 GHz [2,[4][5][6], targeting applications like UWB communications or hard disk drives. Nevertheless, bands much higher, of about 10GHz, are to be addressed in the near future.…”
