A 10.7-MHz fully balanced, high-Q, wide-dynamic-range current-tunable Gm-C bandpass filter is presented. The technique is relatively simple based on three fully balanced components, i.e. an adder, a low-Q-based bandpass filter and a differential amplifier. The high-Q factor is possible through a tunable bias current. As a simple example at 10.7 MHz, the paper demonstrates the high-Q factor of 267, the low total output noise of 2.089 Vrms, the 3rd-order intermodulation-free dynamic range (IMFDR3) of 82.59 dB and the wide dynamic range of 103 dB at 1% IM3. The center frequency is current tunable over 3 orders of magnitude. Comparisons to other 10.7-MHz Gm-C approaches are also included.
