A current-to-frequency converter using switched-current (SI) circuits is proposed. The SI integrator with a hold-and-reset switch can control integration by the output signals. In the proposed circuit the oscillation frequency can be controlled by the input current, and the circuit is operated in the current domain. This is verified by HSPICE simulations.
