Compare the three types of bridge circuits:
constant-voltage bridge; constant-current bridge; and half-bridge, in terms of
nonlinearity, effect of change in temperature, and cost. Obtain an expression
for the percentage error in a half-bridge circuit output due to an error δvref
in the voltage supply vref. Compute the percentage error in the
output if the voltage supply has a 1% error
