This paper presents a fully reconfigurable lowpower filter that is composed of a cascade of floating-gate transistor-capacitor (FGT-C) biquadratic sections suitable for biomedical applications. The proposed FGT-C filter provides both the lowpass and bandpass outputs to the following stage with all filter parameters reconfigurable, including the gains, natural frequency, quality factor, DC levels for input and outputs. The filter topology exhibits good modularity so that the biquadratic sections can be cascaded and scaled up to implement highorder frequency responses easily with efficient area and power consumption. A prototype chip has been fabricated in a 0.35 m 2P4M CMOS process and each FGT-C biquadratic filter occupies an area of 0.0313 mm 2 . From measurement results, the filter consumes 118.4 nW of power with a dynamic range of 45.5 dB while operating at 1.8 V power supply with a 10 kHz bandwidth.

“…As a consequence, the obtained AFs will consume high power and produce high output noise depended on the number of transistor s used. An attempt to reduce the circuit complexity of an AF has been reported in [8] by employing the concept of a transistorized filter in a single-branch circuit structure [9]. Although an extremely compact AF circuit was successfully achieved, the input voltage signal swing of the AF circuit is limited to a few tens milivolt only.…”

A compact 1 st -order analog allpass filter operating from a 1.5 V DC supply is presented. The proposed circuit is formed by a handful of subthreshold pMOS transistors, two capacitors and one current source. Verified by circuit simulations using RF Spectre and the AMS 0.35-micron CMOS parameters, the proposed filter consumes 300 nW quiescent power and contributes output noise voltage of 0.03 mV rms while providing a 90-degree phase-shift frequency of 22 kHz. The differential input signal voltage swing and dynamic range are 0.1 V p and 67.7 dB, respectively.
