Some comment on noise is appropriate to understand the
capability of this circuit. A 150
resistor and R1 and R2
gain resistors connected to a noiseless amplifier will generate
220 nV of noise in a 20 kHz bandwidth, or 73 dB below a 1 mV
reference level. Any practical amplifier can only approach this noise
level; it can never exceed it. With the OP27 and T1 specified, the
additional noise degradation will be close to 3.6 dB (or
–
69.5 refer-
enced to 1 mV).
