Abstract
An oscillator circuit arrangement includes a switched capacitor circuit at least one capacitor selectively coupled to one of a supply terminal and a terminal for ground potential. A chopper circuit is disposed between the switched capacitor circuit and a comparator. The chopper circuit selectively couples one of input terminals and a reference potential terminal to its output terminals. A buffer circuit is coupled to the output of the comparator circuit. The buffer circuit is connected to the switched capacitor circuit and to the chopper circuit to control selective coupling operations therein.
