摘要： An oscillator includes a reference stage and multiple phase stages. The reference stage has a reference transistor having a gate coupled to a voltage reference and a drain coupled to a reference current source. Each phase stage includes a transistor, two current sources, a capacitor, switch, inverter, and latch. The transistor has a drain coupled to a first current source, a gate coupled to a node and a source coupled to the reference transistor's source. The capacitor and switch couple between the node and ground. The second current source couples to the node. The transistor's drain couples to the inverter's input. The inverter's output couples to the latch's set input. The latch's output couples to the switch. The inverter output also couples to the reset input of a subsequent phase stage's latch. The inverter output for a last stage couples to the reset input of a first stage latch.

摘要： A method for generating an oscillator signal uses a multiphase oscillator having a plurality of input stages and a reference stage. Each input stage produces an input stage voltage that represents a phase for the oscillator. The input stage voltages produced by each of the input stages are compared to a reference voltage produced by the reference stage. An input stage having a maximum input stage voltage is selected and an output of the selected input stage having the maximum input stage voltage is changed. A current need of the oscillator is detected with a negative feedback loop coupled to the reference stage. An appropriate supply current is provided to each input stage with the negative feedback loop.

Each channel map is accompanied by a channel map identifier which identifies the source of the television transmission and a geographic identifier. The source of a television transmission is automatically detected by monitoring the radio-frequency spectrum allocations of telecast stations. The geographic area identifier is determined by comparison with a user inputted geographic area identifier.
