THS3202 www.ti.com SLOS242F – SEPTEMBER 2002 – REVISED JANUARY 2010 APPLICATION INFORMATION INTRODUCTION The THS3202 is a high-speed, operational amplifier configured in a current-feedback architecture. The device is built using Texas Instruments BiCOM-II process, a 15-V, dielectrically isolated, complementary bipolar process with NPN and PNP transistors possessing fTs of several GHz.
PAGE 18
THS3202 SLOS242F – SEPTEMBER 2002 – REVISED JANUARY 2010 www.ti.com The THS3202 amplifier exhibits very good distortion performance and bandwidth with the capability of utilizing up to 15-V supplies. Their excellent current drive capability of up to 115 mA driving into a 20-Ω load allows for many versatile applications. One application is driving a twisted pair line (for example, a telephone line). Figure 77 shows a simple circuit for driving a twisted pair differentially. +6 V THS3202(a) 0.

THS3202 www.ti.com SLOS242F – SEPTEMBER 2002 – REVISED JANUARY 2010 NOISE CALCULATIONS Noise can cause errors on very small signals. This is especially true for amplifying small signals coming over a transmission line or an antenna. The noise model for current-feedback amplifiers (CFB) is the same as for voltage feedback amplifiers (VFB).
PAGE 20
THS3202 SLOS242F – SEPTEMBER 2002 – REVISED JANUARY 2010 www.ti.com This brings up another noise measurement usually preferred in RF applications, the noise figure (NF). Noise figure is a measure of noise degradation caused by the amplifier. The value of the source resistance must be defined and is typically 50 Ω in RF applications.

A 50-Ω environment is not necessary onboard, and in fact, a higher impedance environment improves distortion as shown in the distortion versus load plots.

THS3202 SLOS242F – SEPTEMBER 2002 – REVISED JANUARY 2010 www.ti.com GENERAL CONFIGURATIONS A common error for the first-time CFB user is creating a unity-gain buffer amplifier by shorting the output directly to the inverting input. A CFB amplifier in this configuration oscillates and is not recommended. The THS3202, like all CFB amplifiers, must have a feedback resistor for stable operation. Additionally, placing capacitors directly from the output to the inverting input is not recommended.
