Wide Tuning Range Active Rf Bandpass Filter With Mos Imt

With a careful scaling of the selected active devices and with a suitable bias topology the q of the active inductor can be simply controlled varying the bias voltage.

Hara active inductor. Hara active inductors shown in fig234 employ only a mosfet and a resistor. Since the gate voltage is kept at vdd vgs is reduced. In this section we shall discuss about the several active inductor parameters such as inductive range tunability quality factor power consumption linearity supply voltage sensitivity and noise.

An increase of the input current will result in an increase in the voltage at the input node. In this paper we propose a lc resonator circuit using haras active inductor for adiabatic logic. The feedback operation of nmos hara active inductor is as the followings.

The proposed circuit consists of four mos transistors colpitts oscillator and an active inductor. It is seen that the oscillation frequencyofthevcowithhara activeinductorloadsisapproximately twice that of the vco with the resistor loads. They are indeed gyrator c active inductors.

In order to define the active inductor circuit few parameters need to be measured. However the high cost currently involved in the use of these technologies restricts their applications to very specific integrated circuits ics. Active inductor with feedback resistor based voltage controlled oscillator design for wireless applications this paper presents active inductor based vco design for wireless applications based on analysis of active inductor models weng kuo cascode active inductor amp.

Performance parameters of active inductors. The proposed active inductor is well suited even for ka band applications and makes use of only few active elements. Simulated output voltage of a 4stage crosscoupled ring vco with hara active inductor loads.

The proposed circuit consists of four mos transistors colpitts oscillator and an active inductor. Liang regular cascode active inductor with feedback resistor technique. Hara active inductor figures 2 and 3 show haras active inductor 11 and its small signal model respectively.

Active inductors are generally fabricated by using semi insulating gallium arsenide gaas technologies. This circuit require no inductor and can be produced two phase sinusoidal clocking. In the last three decades two major types of active inductors have been reported for rf microwave and more recently millimeter wave.

This circuit is indeed gyrator c active inductor. In the first approach the inductors are realized with only active circuits. This circuit require no inductor and can be produced two phase sinusoidal clocking.
