摘要： In an electronic inductor circuit, an operational amplifier drives the base of the electronic inductor transistor, and receives negative feedback from the emitter of the transistor. The transistor and operational amplifier combine to form a voltage-controlled current source (VCCS) with respect to the loop current. A voltage divider connected across the rectified Tip and Ring voltage (or another node of the circuit at an equivalent voltage) provides a DC reference to the positive input of the operational amplifier, so that the line current automatically increases with an increase in line voltage. A capacitor couples the transmit signal driver to the positive input of the operational amplifier. This electronic inductor circuit can be driven using a low voltage supply and provides sufficient linearity for high-speed modem applications.

摘要： A balance-to-single signal converting circuit of the present invention includes an anti aliasing filter comprising an operational amplifier supplied at a non-inversion input terminal with a voltage obtained by dividing a power source voltage, for example Vdd, by resistors coupled between a power source and, for example, a ground. Each resistors may have a resistance value about twice as large as that of a resistor coupled between an inversion input terminal of the operational amplifier and the output of the operational amplifier. Accordingly, a balance-to-single signal converting circuit can be constructed without inputting to the AAF a reference voltage from a reference voltage generating circuit which is supplied to a switched capacitor filter.

摘要： A gyrator based resonator comprises first and second differential amplifiers cross coupled to form a quadrature phase voltage controlled oscillator. The differential amplifier circuits include matched transistor pairs and associated transconductance adjusting components to control the resonant frequency of the resonator. Transconductance delay and admittance loss elements are also provided and these elements serve to control the loop gain of the resonator. A loop gain greater than unity results in the resonator oscillating while a loop gain less than unity produces a bandpass filter. A resonator having gain less than unity may be slaved to a similar resonator having gain adjusted to be greater than unity thus creating a low noise oscillator and tracking filter.

摘要： [Object] To propose a wireless communication apparatus capable of realizing separation of transmission signals and reception signals with a low power consumption and a small size.
[Solution] Provided is a wireless communication apparatus including: a gyrator that includes at least four terminals; a single-phase differential converter that mutually converts single-phase signals and differential signals; a low-noise differential amplifier that amplifies reception signals that the gyrator outputs; and a differential power amplifier that amplifies transmission signals to be output to the gyrator. The gyrator transmits signals from a first terminal and a second terminal in the direction of a third terminal and a fourth terminal. Any of the single-phase differential converter, the low-noise amplifier, and the power amplifier are connected to the first terminal and second terminal, the third terminal and fourth terminal, the first terminal and third terminal, and the second terminal and fourth terminal of the gyrator.

摘要： A balanced gyrator comprises interconnected pairs of single-ended inverting class AB transconductors (TC1 to TC4) fabricated from MOSFETs together with common mode feedback circuits (26) connected between balanced inputs (18,19) and outputs (22, 23). Peaking of the frequency response resulting from distortion due to the creation of a high frequency parasitic feedthrough path in the transconductors is overcome by the provision in each of the transconductors (TC1 to TC4) of a non-reciprocal feedback capacitance (Cf) which renders the feedthrough capacitance reciprocal thereby neutralising the feedthrough capacitance of the gyrator.The devices include a filter (Figure 8, not shown) and a transceiver (Figure 10, not shown).

摘要： The invention relates to a filter circuit and a method for making a filter circuit comprising at least one gyrator core section (GCi) having four inverters mutually connected in a loop configuration between a pair of input terminals (i_1; i_2) and a pair of output terminals (o_1; o_2). At least one common mode feedback section (CMIi, CMOi) is provided between the pair of input terminals and/or the pair of output terminals. The common mode feedback section comprises two series connections respectively formed by an inverter and a short-sectioned inverter connected antiparallelly between the input terminals or the output terminals. The inverters may be constituted by a MOS, CMOS or BiCMOS or bipolar transistor. According to the invention, the channel region dimensions of the transistors of the gyrator core section and/or the common mode feedback section are selected such that the relationship g*C ≥ gm*cm is fulfilled, where g is the effective conductive loading of the gyrator core section terminals, C is the effective capacitive loading of the gyrator core section terminals, gm is the effective gyration constant of the gyrator core section, and cm is the effective transcapacitance of the gyrator core section.
