摘要： An oscillator circuit includes an electrical load, a first metal oxide semiconductor (MOS) devise, a second MOS device, and a negative feedback circuit. The electrical load is coupled between a first node and a second node. The first MOS device is coupled between the first node and a third node, and controls a first current flowing from the first node to the third node. The second MOS device is coupled between the second node and a fourth node, and controls a second current flowing from the second node to the fourth node. A positive feedback circuit is formed with the first and second MOS devices. The positive feedback circuit has inputs from the first and second nodes and outputs to the first and second MOS devices. The negative feedback circuit has inputs from the third and fourth nodes and outs to the first and second MOS devices.

摘要： A circuit includes a switched-capacitor array for converting a digital signal into a corresponding amount of electric charge, a switching circuit, and a continuous-time reconstruction filter circuit. The switched-capacitor array includes a plurality of capacitors and a summing node to which the plurality of capacitors are connected. The switching circuit is coupled between the summing node and the continuous-time reconstruction filter circuit, and supplies a pulsed current signal to the continuous-time reconstruction filter circuit. The circuit may further include a gain stage coupled between the summing node and the switching circuit, for controlling a gain of the pulsed current signal. The gain stage may include a coupling capacitor. A digital signal is supplied to the switched capacitor array and converted into a corresponding amount of electric charge. The electric charge is supplied as a pulsed current signal to the continuous-time reconstruction filter circuit without converting into a voltage signal.
