2 Distortion from Power Supplies Power supplies can contribute distortion as well as noise Power supplies have non-zero Zout Output impedance of an LDO or switching converter Op amp supply drops for a half-cycle of the output waveform Half-wave rectified sine waves have even harmonics: 2

6 Percentage of Rated Voltage Percentage of Rated Capacitance Percentage of Rated Capacitance (%) Distortion From Ceramic Capacitors Capacitance of Class II & III ceramics will vary greatly with the applied voltage This is known as the voltage coefficient of capacitance or VCC Causes: Dielectric constant changes with the intensity of an applied electric field Capacitor dimensions change with an applied electric field Reverse piezoelectric effect (ceramic capacitors) Electrostatic force ( Polyester film capacitors) The top graph shows a typical voltage coefficient curve from a manufacturer s datasheet The bottom graph shows how the value of the capacitor will change in real time for an applied sine wave % % 95.00% 90.00% 85.00% 80.00% 75.00% Example Voltage Coefficient of an X7R Capacitor 70.00% 0.00% 10.00% 20.00% 30.00% 40.00% 50.00% 60.00% 70.00% 80.00% 90.00% % % 90.00% 70.00% 50.00% 30.00% 10.00% % % % % % Percentage of Rated Voltage Change in Capacitance for an Applied Sine Wave % % 95.00% 90.00% 85.00% 80.00% 75.00% % 70.00% Time Voltage Capacitance 6
7 What About AC Coupling Capacitors? 1uF (6.3V) / 10kΩ AC coupling capacitors may also produce distortion Voltage across the coupling capacitor increases as the low frequency cutoff is approached. 10uF (50V) / 10kΩ 10uF (6.3V) / 10kΩ Place the low frequency corner >2 decades below desired passband. f C 2 1 R IN C IN 10uF (6.3V) / 100kΩ Capacitor Shorted 7
8 Distortion from Surface Mount Resistors Thick film resistors may produce distortion Voltage coefficient of the resistive element Usually only seen for large signal voltages (>3V RMS ) Effect is worst for small package sizes and high resistance values Thick Film, 0603 Thin Film,
9 Distortion from External ESD Protection The capacitance of ESD diodes varies according to the equation: The signal across the ESD diode causes its capacitance to change Draws a non-linear current Converted to a non-linear voltage by source impedance Chose diodes with the lowest junction capacitance possible! Place them at low impedance nodes Non-linear current drawn does not produce a non-linear voltage C D C DO V 0.7 R 1 9
10 CMOS Switch Impedance CMOS Switches are composed of NMOS and PMOS devices in parallel Allows them to conduct current in both directions Control voltage (V G ) is typically constant Signal voltage (V S ) is variable Changing V GS modulates the on-resistance of the FETs Varying impedance creates distortion Worst for high load currents / low load impedances Increase load impedance Close feedback loop around the switch On-Resistance PMOS NMOS Combined V- Input Voltage V+ V- INPUT S G D NMOS OUTPUT V+ S G D PMOS CONTROL Reducing Distortion from CMOS Analog Switches Caldwell, 1Q2015 AAJ 10
11 Reducing Distortion From External Sources Minimizing distortion from power supplies Chose op amps with high PSRR in the desired passband Design power supplies to limit their output impedance Bulk decoupling capacitors, linear regulators, short PCB traces Capacitors Use NP0/C0G ceramic or Polypropylene film capacitors in the signal path For AC coupling capacitors set f c >2 decades below the passband Resistors Use thin film surface mount resistors (Larger packages are better) Through-hole metal film resistors are also very good ESD Protection CMOS Switches 11
