The author demonstrates blocking charge oscillation in a series array of two tiny tunnel junctions with an island electrode having a resistive ground path. In the array, single-electron tunneling carries electric charge discretely into the island, while charge leakage through the resistive path to the ground reduces the island charge continuously. The combination of the discrete and continuous charge transfer eventually results in blocking oscillation of the island charge. Numerical Monte Carlo simulation demonstrates the blocking oscillation. Bias conditions for the blocking oscillation are analytically derived.
