20120206199 | Method and apparatus to linearize transconductors by predistortion - A transconductor for providing an output current that is linear in the input voltage (Vin) comprises a main output transconductor (Ms, Mc) and a model transconductor (Msr | 08-16-2012 |
20100253441 | VARIABLE INDUCTOR - A variable simulated inductor comprises an integrator connected to receive the voltage across the input to the circuit. The output of the inductor is connected to a control terminal of a transconductor connected across the input of the circuit. The gain of the transconductor is electronically controllable in order to control the inductance of the circuit. An oscillator using a variable simulated inductor and a piezoelectric resonator connected in parallel is also provided. | 10-07-2010 |
20100182091 | METHOD AND APPARATUS TO LINEARIZE TRANSCONDUCTORS BY PREDISTORTION - A transconductor for providing an output current that is linear in the input voltage (Vin) comprises a main output transconductor (Ms, Mc) and a model transconductor (Msr | 07-22-2010 |
20100117712 | MIXER WITH SHORTING SWITCH - A double-balanced mixer is provided having a shorting switch connecting the signal inputs to the mixer core. A timer circuit provides pulses to close the switch, thereby shorting those inputs at times when the switches of the mixer core are switching. This is done because non-linear components in the output are produced at those times and therefore they can be removed if the signal input is shorted at those times. | 05-13-2010 |
