In the next section, in a short, the basic propThe frequency response of a high-Q seconderties of the mode 1 are summarized. The proporder ̄lter section is 2Q times more sensitive erties of elliptic-function ̄lters with poles on a to the variations in pole-frequency than it is to circle are presented in the third section. Modivariations in Q-factors. All useful biquad cir̄cations of the mode 1 are...

We present a novel multifunction inverse biquad configuration based on current feedback operational amplifiers (CFOAs) and grounded passive elements. The proposed scheme can be used to realize inverse lowpass, inverse bandpass and inverse highpass filter functions. The relevant coefficients of the inverse filters are orthogonal adjustable by independent passive elements. All the passive element...

A balanced transconductance-C biquad implemented in the digital subset of a 0.9-um CMOS process operates at frequencies up to 450 MHz and Q factors from a nominal value near 1 to approximately 100 with 30-40-dB dynamic range. By switching in capacitors and adjusting control voltages it can be tuned to below 30 MHz, demonstrating the capability of operating over the entire VHF range. Active area...

On-chip automatic tuning circuit with proposed integration level approximation technique, designed in a 0.65m 3.3V CMOS process for tuning of the variation passive component. To verify tunning efficiency of proposed circuit, three types of 2nd-order biquad RC active filters were used. The cut-off frequency (fc) error of filter with proposed tuning circuit can be reduced by new algorithm that co...

Abstract  In his paper a new current-controlled conveyor (CCCII) in CMOS technology is presented. It features, low supply voltage (±0.7), low power consumption, low circuit complexity, rail to rail operation and wide range parasitic resistance ( ). The circuit has been successfully employed in a multifunction biquad filter. Simulation results by HSPICE show high performance of the circuit and c...

This paper presents a current-processing current-controlled universal biquad filter. The proposed filter employs only two current controlled current conveyor transconductance amplifiers (CCCCTAs) and two grounded capacitors. The proposed configuration can be used either as a single input three outputs (SITO) or as three inputs single output (TISO) filter. The circuit realizes all five different...

Its necessary a technology or advanced device that can observe atmospheric data and send it to an earth station (ground segment). Data of information on air pressure, temperature, humidity, wind speed are ordinarily needed by the Meteorological, Climatological Geophysical Agency (BMKG) in weather forecasts. To be able receive sent payload, ground segment requires receiver equipped with antenna ...

This paper presents a universal current-controlled current-mode biquad filter employing current controlled current conveyor trans-conductance amplifiers (CCCCTAs). The proposed filter employs only three MOCCCCTAs and two grounded capacitors. The proposed filter can simultaneously realize low pass (LP), band pass (BP), high pass (HP), band reject (BR) and all pass (AP) responses in current form ...
