摘要: A high impedance is implemented in the input bias path of an integrated instrumentation amplifier. The implementation includes a normally on transistor switch. signal from output amplifier used to turn switch off provide requisite impedance. Otherwise, low for proper biasing. circuit adapted encoded signals such as occur capacitive coupled credit card encoding circuits.
