PARAMETER MEASUREMENT INFORMATION
A close approximation of the input offset voltage can be obtained by using a binary search method to vary the
differential input voltage while monitoring the output state. When the applied input voltage differential is equal,
but opposite in polarity, to the input offset voltage, the output changes states.
Figure 2 illustrates a practical circuit for direct dc measurement of input offset voltage that does not bias the
comparator in the linear region. The circuit consists of a switching-mode servo loop in which U1A generates
a triangular waveform of approximately 20-mV amplitude. U1B acts as a buffer, with C2 and R4 removing any
residual dc offset. The signal is then applied to the inverting input of the comparator under test, while the
noninverting input is driven by the output of the integrator formed by U1C through the voltage divider formed
by R9 and R10. The loop reaches a stable operating point when the output of the comparator under test has
a duty cycle of exactly 50%, which can only occur when the incoming triangle wave is sliced symmetrically or
when the voltage at the noninverting input exactly equals the input offset voltage.
The voltage divider formed by R9 and R10 provides an increase in input offset voltage by a factor of 100 to
make measurement easier. The values of R5, R8, R9, and R10 can significantly influence the accuracy of the
reading; therefore, it is suggested that their tolerance level be 1% or lower.
Measuring the extremely low values of input current requires isolation from all other sources of leakage current
and compensation for the leakage of the test socket and board. With a good picoammeter, the socket and board
leakage can be measured with no device in the socket. Subsequently, this open-socket leakage value can be
subtracted from the measurement obtained with a device in the socket to obtain the actual input current of the
device.
