    摘要: In a current-mode transconductor-C integrator the non-linearity of the voltage-to-current conversion of a transconductor (17) is corrected by means of a differentiator (3) which supplies a current (i d ) which is proportional to the derivative of a current (if), which is proportional to the transconductor output current (i out ), with respect to the transconductor control voltage (v), which current (i d ) is divided by means of a current divider (9) into an input current (i in ) and is applied as a quotient current (iq) to an integrating capacitor (13) across which a voltage (v) is built up, which voltage is converted into an output current (i out ) by the transconductor. This results in an output current (i out ) which is linearly proportional to the integral of the input current (i in ) without distortion caused by the non-linear voltage-to-current characteristic of the transconductor (17).

    摘要: A switched-current integrator circuit (50) employs track-and-hold circuits (52,54) in which the gates of the current mirror FET switches (M1,M2) are connected together to form a common gate node (58) to double the effective holding capacitance. Additionally, the common gate node (58) is coupled to the input terminal (16) through a CMOS switch (62,64) so that parasitic clock feed-through is essentially cancelled to minimize DC offset voltages (V1,V3 in FIG. 4).

    摘要: A bilinear integrator comprises a first input (1) and a second input (5). The input (1) is connected to the input of a first current memory cell formed by two transistors (T1, T2), capacitor (C1), and switch (S1). The first current memory cell is arranged to store a current applied to its input during a first portion φ of each sampling period and to reproduce that current at its output during a second portion φ of the succeeding sampling period. The second input (5) is connected to the input of a second current memory cell formed by three transistors (T3, T4 and T5), capacitor (C2) and switch (S3) via the switch (S2). During a second portion φ of each sampling period the current applied to the second input (5) and the current produced at the output of the first current memory cell are applied to the input of the second current memory cell. The second current memory cell has two outputs (from the drain electrodes of transistors (T4, T5)). The first output is fed back to the input of the first current memory cell while the second output is fed to the integrator output (8).

    摘要: An electronic integration circuit comprises an integrator input element that provides a final power stage of the electronic integration circuit and provides a constant drain current in a direct current state that controls a current of the first stage driver; and an inductive load driver constructed and arranged to drive an inductive element as a voltage follower stage. The inductive load driver processes a linear gate current to control a current output to the inductive element. A capacitor is between the first stage driver and the integrator input element. A sum of a gate-source voltage of the first stage driver and a gate-source voltage of the integrator input element is provided as an integrator input to the capacitor. The capacitor performs a linear current ramp integration operation to provide a first exponential voltage shape across the inductive element required for driving the inductive element in accordance with the controlled current output in a second exponential voltage shape.
