Design an EKG amplifier interface to a 6811/6812. The biopotential is a ±5-mV signal measured between the left and right arms using silver-silver chloride electrodes. A third electrode is placed in the right leg and is used as a reference. To make the entire system battery-operated, low-power rail-to-rail TLC2274 op amps will be used, each powered with +5 and ground. Notice that the analog system uses the 2.5V signal as its reference.
Design the preamplifier that has the following characteristics: differential input, gain=10, good CMRR, high Zin, low Zout, and bandwidth>200Hz. Show resistors values, but not pin numbers.
