4 www.johansondielectrics.com the x2y ? design - a balanced, low esl, ?capacitor circuit? the x2y ? capacitor design starts with standard 2 terminal mlc capacitor?s opposing electrode sets, a & b, and adds a third electrode se t (g) which surround each a & b electrode. the result is a higly vesatile three node capacitive circuit containing two tightly matched, low inductan ce capacitors in a compact, four- terminal smt chip. amplifier input filter example in this example, a single johanson x2y ? component was used to filter noise at the input of a dc instrumentation amplifier. this reduced component count by 3-to-1 and costs by over 70% vs. conventional filter components that included 1% film y-capacitors. parameter x2y ? 10nf discrete 10nf, 2 @ 220 pf comments dc offset shift < 0.1 v < 0.1 v referred to input common mode rejection 91 db 92 db source: analog devices, ?a designer?s guide to instrumentation amplifiers (2nd edition)? by charles kitchin and lew counts x2y ? circuit 1: filtering circuit 1 connects the x2y ? filter capacitor across two signal lines. common-mode noise is filtered to ground (or reference) by the two y-capacitors, a & b. because x2y ? is a balanced circuit that is tightly matched in both phase and magnitude with respect to ground, common-to-differential mode noise conversion is minimized and any differential-mode noise is cancelled within the device. the low inductance of the capacitors extends their high frequency attenuation considerably over discrete mlcs. g1 g2 a b signal 1 signal 2 ground x2y ? f ilter & d ecoupling c apacitors x2y ? circuit 2: power bypass / decoupling circuit 2 connects the a & b capacitors in parallel doubling the total capacitance while reducing the inductance. x2y capacitors exhibit up to 1/10th the device inductance and 1/5th the mounted inductance of similar sized mlc capcitors enabling high-performance bypass networks with far fewer components and vias. low esl delivers improved high frequency performance into the ghz range. power ground g1 g2 a b gsm rfi attenuation in audio & analog gsm handsets transmit in the 850 and 1850 mhz bands using a tdma pulse rate of 217hz. these signals cause the gsm buzz heard in a wide range of audio products from headphones to concert hall pa systems or ?silent? signal errors created in medical, industrial process control, and security applications. testing was conducted where an 840mhz gsm handset signal was delivered to the inputs of three different amplifier test circuit configurations shown below whose outputs were measured on a hf spectrum analyzer. 1) no input filter, 2 discrete mlc 100nf power bypass caps. 2) 2 discrete mlc 1nf input filter, 2 discrete mlc 100nf power bypass caps. 3) a single x2y 1nf input filter, a single x2y 100nf power bypass cap. x2y configuration provided a nearly flat response above the ambient and up to 10 db imrpoved rejection than the conventional mlcc configuration.

(the total capacitance of x2y (circuit 2) is twice the value, or 200nf and 98nf in this example.) the sigle x2y is clearly superior to the three paralleled mlcs.
