Current biasing of the LSB ladder addresses this issue by employing active circuitry. To prevent false alarms produced by a single sensor activation, the alarm will be triggered only when at least two sensors activate simultaneously. It can be defined by the numbers of bits or its step size. From This Paper Figures, tables, and laddwr from this paper.

Although limited by component mismatches, resolution of these converters is typically enhanced by calibration solutions such as laser ladeer or corrective active circuitry. The usage of the LSB ladder incurs a penalty in dynamic performance due to the added output resistance and switch matrix parasitic capacitance.
