Abstract
A counter circuit includes a first Johnson counter circuit and a second Johnson counter circuit coupled in cascade. Each Johnson counter circuit includes a clock input, a data input, a first clock data output, a second clock data output and a feedback from the second clock data input to first data input. The clock input of the first Johnson counter circuit is configured to receive an input clock signal. The clock input of the second Johnson counter circuit is connected to the second clock data output of the first Johnson counter circuit. A ripple counter circuit has a clock input and additional clock data outputs. The clock input of the ripple counter circuit is connected to the second clock data output of the preceding Johnson counter circuit.
