Abstract:
This paper introduces three new OTA-C universal biquad filters which offers almost all of the desirable features (as expected in a good biquad) simultaneously with any major tradeoffs. The two biquads (a VM-based biquad and a CM-based biquad) are combined efficiently to form a hybrid biquad that can be digitally controlled to convert into either of the two with similar responses. The workability of the new circuits has been well established by SPICE simulation results of their CMOS-implementable versions.

Abstract:
Certain biquad filters structures are characterized by a reduction of the attenuation at higher frequencies, caused by the finite value of the output resistance of the operational amplifier. In this paper, the design of the combined BP filter without the described decreasing is discussed for which one possible solution is to replace one of the biquads with another biquad that does not have this property. The result is a combined filter from different structures. The methodology to design a combined BP filter without the described decreasing is described in detail with the parameters of such bi

Abstract:
LLCL filters for grid-tied inverters have been adopted to get better performance for the harmonics near the switching frequency than commonly used LCL filters. However, the resonant peak caused by a pair of unstable resonance poles of the LLCL filters is introduced and makes the system become unstable. In this paper, a biquad filter composed of a notch filter and a resonator is introduced to restrain the resonant peak. In this method, the resonance point and the notch point of the biquad filter are placed at the appointed frequency, and the resonant peak is transferred to the stable area by ph

Abstract:
Multi-GHz lowpass filters are key components for many RF applications and are required for the implementation of integrated high-speed analog-to-digital and digital-to-analog converters and optical communication systems. In the last two decades, integrated filters in the Multi-GHz range have been implemented using III-V or SiGe technologies. In all cases in which the size of passive components is a concern, inductorless designs are preferred. Furthermore, due to the recent development of high-speed and high-resolution data converters, highly linear multi-GHz filters are required more and more.

Abstract:
Low-pass filters with bandwidths larger than several GHz are required in many applications, such as anti-aliasing filters in high-speed ADCs and pulse-shaping filters in high-speed DACs. In highly integrated applications, low area occupation and power consumption are key specifications, so inductor-less implementations are to be preferred. Furthermore, full CMOS implementations provide an advantage in terms of technology availability and cost.

The Kerwin-Huelsman Newcomb (KHN) biquad is the natural choice for use as a ‘universal’ filter building block out of the several existing 3-amplifier biquadratic filter sections based on the two integrator loop or state variable realization of 2nd order systems. A modified version of the KHN biquad, which is electronically tunable almost linearly over a decade range of center frequency, is presented. For electronic tunability, instead of the direct use of a FET as a voltage variable resistance to control the time constants of the integrators, a novel approach of using voltage-controlled variab
