Abstract: A circuit includes a first transistor, a second transistor, and a sense transistor. The first current terminals of the first and second transistors are coupled together at a power supply node. The control terminals of the second and third transistors are coupled together. The second current terminals of the first, second, and third transistors are coupled together. The sense resistor is coupled between the first current terminals of the first and second transistors and the first current terminal of the third transistor. The first and second transistors are configured such that during a first mode of operation, current to a load flows through the first and second transistors, and during a second mode of operation, current to a load is discontinued through the first transistor yet flows through the second transistor.

Abstract: An FLL (frequency locked loop) oscillator/clock generator includes a free-running oscillator (such as a ring oscillator), and generates an FLL_clk with an FLL-controlled frequency fOSC. The FLL control loop includes a switched capacitor resistor divider that converts fOSC to a resistance, generating an FLL feedback voltage Vfosc used to generate a loop control signal OSC_cntrl input to the oscillator. In response, the oscillator frequency locks FLL_clk to fosc. In an example implementation, the FLL oscillator/clock operates with spread spectrum clocking (SSC) that provides triangular SSC modulation based on a truncated RC transition voltage generated as a negative feedback to an RC relaxation oscillator, with truncation based on switched tripping threshold voltages generated a positive feedback to the RC relaxation oscillator.
